build: move e2e dependencies into e2e/go.mod

Several packages are only used while running the e2e suite. These
packages are less important to update, as the they can not influence the
final executable that is part of the Ceph-CSI container-image.

By moving these dependencies out of the main Ceph-CSI go.mod, it is
easier to identify if a reported CVE affects Ceph-CSI, or only the
testing (like most of the Kubernetes CVEs).

+
+You can contribute by using the library, opening issues, or opening pull requests.
+
+## Bug reports and security vulnerabilities
+
+Most issues are tracked publicly on [GitHub](https://github.com/fxamacker/cbor/issues). 
+
+To report security vulnerabilities, please email faye.github@gmail.com and allow time for the problem to be resolved before disclosing it to the public.  For more info, see [Security Policy](https://github.com/fxamacker/cbor#security-policy).
+
+Please do not send data that might contain personally identifiable information, even if you think you have permission.  That type of support requires payment and a signed contract where I'm indemnified, held harmless, and defended by you for any data you send to me.
+
+## Pull requests
+
+Please [create an issue](https://github.com/fxamacker/cbor/issues/new/choose) before you begin work on a PR.  The improvement may have already been considered, etc.
+
+Pull requests have signing requirements and must not be anonymous.  Exceptions are usually made for docs and CI scripts.
+
+See the [Pull Request Template](https://github.com/fxamacker/cbor/blob/master/.github/pull_request_template.md) for details.

+* If you found a compilation error, please confirm you're using a supported version of Go. If you are, then provide the output of `go version` first, followed by the complete error message.
+
+## Please don't
+
+Please don't send data containing personally identifiable information, even if you think you have permission.  That type of support requires payment and a contract where I'm indemnified, held harmless, and defended for any data you send to me.
+
+Please don't send CBOR data larger than 1024 bytes by email. If you want to send crash-producing CBOR data > 1024 bytes by email, please get my permission before sending it to me.
+
+## Credits
+
+- This guide used nlohmann/json contribution guidelines for inspiration as suggested in issue #22.

+# CBOR Codec in Go
+
+<!-- [![](https://github.com/fxamacker/images/raw/master/cbor/v2.5.0/fxamacker_cbor_banner.png)](#cbor-library-in-go) -->
+
+[fxamacker/cbor](https://github.com/fxamacker/cbor) is a library for encoding and decoding [CBOR](https://www.rfc-editor.org/info/std94) and [CBOR Sequences](https://www.rfc-editor.org/rfc/rfc8742.html).
+
+CBOR is a [trusted alternative](https://www.rfc-editor.org/rfc/rfc8949.html#name-comparison-of-other-binary-) to JSON, MessagePack, Protocol Buffers, etc.&nbsp; CBOR is an Internet&nbsp;Standard defined by [IETF&nbsp;STD&nbsp;94 (RFC&nbsp;8949)](https://www.rfc-editor.org/info/std94) and is designed to be relevant for decades.
+
+`fxamacker/cbor` is used in projects by Arm Ltd., Cisco, EdgeX&nbsp;Foundry, Flow Foundation, Fraunhofer&#8209;AISEC, Kubernetes, Let's&nbsp;Encrypt (ISRG), Linux&nbsp;Foundation, Microsoft, Mozilla, Oasis&nbsp;Protocol, Tailscale, Teleport, [etc](https://github.com/fxamacker/cbor#who-uses-fxamackercbor).
+
+See [Quick&nbsp;Start](#quick-start) and [Releases](https://github.com/fxamacker/cbor/releases/).  🆕 `UnmarshalFirst` and `DiagnoseFirst` can decode CBOR Sequences.  `cbor.MarshalToBuffer()` and `UserBufferEncMode` accepts user-specified buffer.

+
+`fxamacker/cbor` is a CBOR codec in full conformance with [IETF STD&nbsp;94 (RFC&nbsp;8949)](https://www.rfc-editor.org/info/std94). It also supports CBOR Sequences ([RFC&nbsp;8742](https://www.rfc-editor.org/rfc/rfc8742.html)) and Extended Diagnostic Notation ([Appendix G of RFC&nbsp;8610](https://www.rfc-editor.org/rfc/rfc8610.html#appendix-G)).
+
+Features include full support for CBOR tags, [Core Deterministic Encoding](https://www.rfc-editor.org/rfc/rfc8949.html#name-core-deterministic-encoding), duplicate map key detection, etc.
+
+Design balances trade-offs between security, speed, concurrency, encoded data size, usability, etc.
+
+<details><summary>Highlights</summary><p/>
+
+__🚀&nbsp; Speed__
+
+Encoding and decoding is fast without using Go's `unsafe` package.  Slower settings are opt-in.  Default limits allow very fast and memory efficient rejection of malformed CBOR data.
+
+__🔒&nbsp; Security__
+
+Decoder has configurable limits that defend against malicious inputs.  Duplicate map key detection is supported.  By contrast, `encoding/gob` is [not designed to be hardened against adversarial inputs](https://pkg.go.dev/encoding/gob#hdr-Security).
+
+Codec passed multiple confidential security assessments in 2022.  No vulnerabilities found in subset of codec in a [nonconfidential security assessment](https://github.com/veraison/go-cose/blob/v1.0.0-rc.1/reports/NCC_Microsoft-go-cose-Report_2022-05-26_v1.0.pdf) prepared by NCC&nbsp;Group for Microsoft&nbsp;Corporation.
+
+__🗜️&nbsp; Data Size__
+
+Struct tags (`toarray`, `keyasint`, `omitempty`) automatically reduce size of encoded structs. Encoding optionally shrinks float64→32→16 when values fit.
+
+__:jigsaw:&nbsp; Usability__
+
+API is mostly same as `encoding/json` plus interfaces that simplify concurrency for CBOR options.  Encoding and decoding modes can be created at startup and reused by any goroutines.
+
+Presets include Core Deterministic Encoding, Preferred Serialization, CTAP2 Canonical CBOR, etc.
+
+__📆&nbsp;  Extensibility__
+
+Features include CBOR [extension points](https://www.rfc-editor.org/rfc/rfc8949.html#section-7.1) (e.g. CBOR tags) and extensive settings.  API has interfaces that allow users to create custom encoding and decoding without modifying this library.

+### Smaller Encodings with Struct Tags

+
+```Go

+package main
+
+import (
+	"encoding/hex"

+
+![alt text](https://github.com/fxamacker/images/raw/master/cbor/v2.3.0/cbor_struct_tags_api.svg?sanitize=1 "CBOR API and Go Struct Tags")
+
+API is mostly same as `encoding/json`, plus interfaces that simplify concurrency for CBOR options.
+
+## Quick Start
+
+__Install__: `go get github.com/fxamacker/cbor/v2` and `import "github.com/fxamacker/cbor/v2"`.
+
+### Key Points
+
+This library can encode and decode CBOR (RFC 8949) and CBOR Sequences (RFC 8742).
+
+- __CBOR data item__ is a single piece of CBOR data and its structure may contain 0 or more nested data items.
+- __CBOR sequence__ is a concatenation of 0 or more encoded CBOR data items.
+
+Configurable limits and options can be used to balance trade-offs.
+
+- Encoding and decoding modes are created from options (settings).
+- Modes can be created at startup and reused.
+- Modes are safe for concurrent use.
+
+### Default Mode
+
+Package level functions only use this library's default settings.  
+They provide the "default mode" of encoding and decoding.
+
+```go
+// API matches encoding/json for Marshal, Unmarshal, Encode, Decode, etc.
+b, err = cbor.Marshal(v)        // encode v to []byte b
+err = cbor.Unmarshal(b, &v)     // decode []byte b to v
+decoder = cbor.NewDecoder(r)    // create decoder with io.Reader r
+err = decoder.Decode(&v)        // decode a CBOR data item to v
+
+// v2.7.0 added MarshalToBuffer() and UserBufferEncMode interface.
+err = cbor.MarshalToBuffer(v, b) // encode v to b instead of using built-in buf pool.
+
+// v2.5.0 added new functions that return remaining bytes.
+
+// UnmarshalFirst decodes first CBOR data item and returns remaining bytes.
+rest, err = cbor.UnmarshalFirst(b, &v)   // decode []byte b to v
+
+// DiagnoseFirst translates first CBOR data item to text and returns remaining bytes.
+text, rest, err = cbor.DiagnoseFirst(b)  // decode []byte b to Diagnostic Notation text
+
+// NOTE: Unmarshal returns ExtraneousDataError if there are remaining bytes,
+// but new funcs UnmarshalFirst and DiagnoseFirst do not.
+```
+
+__IMPORTANT__: 👉  CBOR settings allow trade-offs between speed, security, encoding size, etc.
+
+- Different CBOR libraries may use different default settings.
+- CBOR-based formats or protocols usually require specific settings.
+
+For example, WebAuthn uses "CTAP2 Canonical CBOR" which is available as a preset.
+
+### Presets
+
+Presets can be used as-is or as a starting point for custom settings.
+
+```go
+// EncOptions is a struct of encoder settings.
+func CoreDetEncOptions() EncOptions              // RFC 8949 Core Deterministic Encoding
+func PreferredUnsortedEncOptions() EncOptions    // RFC 8949 Preferred Serialization
+func CanonicalEncOptions() EncOptions            // RFC 7049 Canonical CBOR
+func CTAP2EncOptions() EncOptions                // FIDO2 CTAP2 Canonical CBOR
+```
+
+Presets are used to create custom modes.
+
+### Custom Modes
+
+Modes are created from settings. Once created, modes have immutable settings.
+
+💡 Create the mode at startup and reuse it. It is safe for concurrent use.
+
+```Go
+// Create encoding mode.
+opts := cbor.CoreDetEncOptions()   // use preset options as a starting point
+opts.Time = cbor.TimeUnix          // change any settings if needed
+em, err := opts.EncMode()          // create an immutable encoding mode
+
+// Reuse the encoding mode. It is safe for concurrent use.
+
+// API matches encoding/json.
+b, err := em.Marshal(v)            // encode v to []byte b
+encoder := em.NewEncoder(w)        // create encoder with io.Writer w
+err := encoder.Encode(v)           // encode v to io.Writer w
+```
+
+Default mode and custom modes automatically apply struct tags.
+
+### User Specified Buffer for Encoding (v2.7.0)
+
+`UserBufferEncMode` interface extends `EncMode` interface to add `MarshalToBuffer()`. It accepts a user-specified buffer instead of using built-in buffer pool.
+
+```Go
+em, err := myEncOptions.UserBufferEncMode() // create UserBufferEncMode mode
+
+var buf bytes.Buffer
+err = em.MarshalToBuffer(v, &buf) // encode v to provided buf
+```
+
+### Struct Tags
+
+Struct tags (`toarray`, `keyasint`, `omitempty`) reduce encoded size of structs.
+
+<details><summary>Example encoding 3-level nested Go struct to 1 byte CBOR</summary><p/>
+
+https://go.dev/play/p/YxwvfPdFQG2
+
+```Go
+// Example encoding nested struct (with omitempty tag)
+// - encoding/json:  18 byte JSON
+// - fxamacker/cbor:  1 byte CBOR
+package main
+
+import (
+	"encoding/hex"
+	"encoding/json"

+	Qux GrandChild `json:",omitempty"`
+}
+
+type Parent struct {
+	Foo Child `json:",omitempty"`
+	Bar int   `json:",omitempty"`
+}
+
+func cb() {
+	results, _ := cbor.Marshal(Parent{})
+	fmt.Println("hex(CBOR): " + hex.EncodeToString(results))
+
+	text, _ := cbor.Diagnose(results) // Diagnostic Notation
+	fmt.Println("DN: " + text)

+	fmt.Println("JSON: " + text)
+}
+
+func main() {
+	cb()
+	fmt.Println("-------------")
+	js()
+}
+```
+
+Output (DN is Diagnostic Notation):
+```
+hex(CBOR): a0
+DN: {}
+-------------
+hex(JSON): 7b22466f6f223a7b22517578223a7b7d7d7d

+

+
+Struct tags simplify use of CBOR-based protocols that require CBOR arrays or maps with integer keys.
+
+### CBOR Tags
+
+CBOR tags are specified in a `TagSet`.
+
+Custom modes can be created with a `TagSet` to handle CBOR tags.
+ 
+```go
+em, err := opts.EncMode()                  // no CBOR tags
+em, err := opts.EncModeWithTags(ts)        // immutable CBOR tags
+em, err := opts.EncModeWithSharedTags(ts)  // mutable shared CBOR tags
+```
+
+`TagSet` and modes using it are safe for concurrent use.  Equivalent API is available for `DecMode`.
+
+<details><summary>Example using TagSet and TagOptions</summary><p/>
+
+```go
+// Use signedCWT struct defined in "Decoding CWT" example.
+
+// Create TagSet (safe for concurrency).
+tags := cbor.NewTagSet()
+// Register tag COSE_Sign1 18 with signedCWT type.
+tags.Add(	
+	cbor.TagOptions{EncTag: cbor.EncTagRequired, DecTag: cbor.DecTagRequired}, 
+	reflect.TypeOf(signedCWT{}), 
+	18)
+
+// Create DecMode with immutable tags.
+dm, _ := cbor.DecOptions{}.DecModeWithTags(tags)
+
+// Unmarshal to signedCWT with tag support.
+var v signedCWT
+if err := dm.Unmarshal(data, &v); err != nil {
+	return err
+}
+
+// Create EncMode with immutable tags.
+em, _ := cbor.EncOptions{}.EncModeWithTags(tags)
+
+// Marshal signedCWT with tag number.
+if data, err := cbor.Marshal(v); err != nil {
+	return err
+}
+```
+
+</details>
+
+### Functions and Interfaces
+
+<details><summary>Functions and interfaces at a glance</summary><p/>
+
+Common functions with same API as `encoding/json`:  
+- `Marshal`, `Unmarshal`
+- `NewEncoder`, `(*Encoder).Encode`
+- `NewDecoder`, `(*Decoder).Decode`
+
+NOTE: `Unmarshal` will return `ExtraneousDataError` if there are remaining bytes
+because RFC 8949 treats CBOR data item with remaining bytes as malformed.
+- 💡 Use `UnmarshalFirst` to decode first CBOR data item and return any remaining bytes.
+
+Other useful functions: 
+- `Diagnose`, `DiagnoseFirst` produce human-readable [Extended Diagnostic Notation](https://www.rfc-editor.org/rfc/rfc8610.html#appendix-G) from CBOR data.
+- `UnmarshalFirst` decodes first CBOR data item and return any remaining bytes.
+- `Wellformed` returns true if the the CBOR data item is well-formed.
+
+Interfaces identical or comparable to Go `encoding` packages include:  
+`Marshaler`, `Unmarshaler`, `BinaryMarshaler`, and `BinaryUnmarshaler`.
+
+The `RawMessage` type can be used to delay CBOR decoding or precompute CBOR encoding.
+
+</details>
+
+### Security Tips
+
+🔒 Use Go's `io.LimitReader` to limit size when decoding very large or indefinite size data.
+
+Default limits may need to be increased for systems handling very large data (e.g. blockchains).
+
+`DecOptions` can be used to modify default limits for `MaxArrayElements`, `MaxMapPairs`, and `MaxNestedLevels`.
+
+## Status
+
+v2.7.0 (June 23, 2024) adds features and improvements that help large projects (e.g. Kubernetes) use CBOR as an alternative to JSON and Protocol Buffers. Other improvements include speedups, improved memory use, bug fixes, new serialization options, etc.   It passed fuzz tests (5+ billion executions) and is production quality.
+
+For more details, see [release notes](https://github.com/fxamacker/cbor/releases).
+
+### Prior Release
+
+[v2.6.0](https://github.com/fxamacker/cbor/releases/tag/v2.6.0) (February 2024) adds important new features, optimizations, and bug fixes. It is especially useful to systems that need to convert data between CBOR and JSON.  New options and optimizations improve handling of bignum, integers, maps, and strings.
+
+v2.5.0 was released on Sunday, August 13, 2023 with new features and important bug fixes.  It is fuzz tested and production quality after extended beta [v2.5.0-beta](https://github.com/fxamacker/cbor/releases/tag/v2.5.0-beta) (Dec 2022) -> [v2.5.0](https://github.com/fxamacker/cbor/releases/tag/v2.5.0) (Aug 2023).
+

+## Who uses fxamacker/cbor
+
+`fxamacker/cbor` is used in projects by Arm Ltd., Berlin Institute of Health at Charité, Chainlink, Cisco, Confidential Computing Consortium, ConsenSys, Dapper&nbsp;Labs, EdgeX&nbsp;Foundry, F5, FIDO Alliance, Fraunhofer&#8209;AISEC, Kubernetes, Let's Encrypt (ISRG), Linux&nbsp;Foundation, Matrix.org, Microsoft, Mozilla, National&nbsp;Cybersecurity&nbsp;Agency&nbsp;of&nbsp;France (govt), Netherlands (govt), Oasis Protocol, Smallstep, Tailscale, Taurus SA, Teleport, TIBCO, and others.
+
+`fxamacker/cbor` passed multiple confidential security assessments.  A [nonconfidential security assessment](https://github.com/veraison/go-cose/blob/v1.0.0-rc.1/reports/NCC_Microsoft-go-cose-Report_2022-05-26_v1.0.pdf) (prepared by NCC Group for Microsoft Corporation) includes a subset of fxamacker/cbor v2.4.0 in its scope.
+
+## Standards
+
+`fxamacker/cbor` is a CBOR codec in full conformance with [IETF STD&nbsp;94 (RFC&nbsp;8949)](https://www.rfc-editor.org/info/std94). It also supports CBOR Sequences ([RFC&nbsp;8742](https://www.rfc-editor.org/rfc/rfc8742.html)) and Extended Diagnostic Notation ([Appendix G of RFC&nbsp;8610](https://www.rfc-editor.org/rfc/rfc8610.html#appendix-G)).
+
+Notable CBOR features include:
+
+| CBOR Feature  | Description  |
+| :--- | :--- |
+| CBOR tags | API supports built-in and user-defined tags.  |
+| Preferred serialization | Integers encode to fewest bytes. Optional float64 → float32 → float16. |
+| Map key sorting | Unsorted, length-first (Canonical CBOR), and bytewise-lexicographic (CTAP2). |
+| Duplicate map keys | Always forbid for encoding and option to allow/forbid for decoding.   |
+| Indefinite length data | Option to allow/forbid for encoding and decoding. |
+| Well-formedness | Always checked and enforced. |
+| Basic validity checks | Optionally check UTF-8 validity and duplicate map keys. |
+| Security considerations | Prevent integer overflow and resource exhaustion (RFC 8949 Section 10). |
+
+Known limitations are noted in the [Limitations section](#limitations). 
+
+Go nil values for slices, maps, pointers, etc. are encoded as CBOR null.  Empty slices, maps, etc. are encoded as empty CBOR arrays and maps.
+
+Decoder checks for all required well-formedness errors, including all "subkinds" of syntax errors and too little data.
+
+After well-formedness is verified, basic validity errors are handled as follows:
+
+* Invalid UTF-8 string: Decoder has option to check and return invalid UTF-8 string error. This check is enabled by default.
+* Duplicate keys in a map: Decoder has options to ignore or enforce rejection of duplicate map keys.
+
+When decoding well-formed CBOR arrays and maps, decoder saves the first error it encounters and continues with the next item.  Options to handle this differently may be added in the future.
+
+By default, decoder treats time values of floating-point NaN and Infinity as if they are CBOR Null or CBOR Undefined.
+
+__Click to expand topic:__
+
+<details>
+ <summary>Duplicate Map Keys</summary><p>
+
+This library provides options for fast detection and rejection of duplicate map keys based on applying a Go-specific data model to CBOR's extended generic data model in order to determine duplicate vs distinct map keys. Detection relies on whether the CBOR map key would be a duplicate "key" when decoded and applied to the user-provided Go map or struct. 
+
+`DupMapKeyQuiet` turns off detection of duplicate map keys. It tries to use a "keep fastest" method by choosing either "keep first" or "keep last" depending on the Go data type.
+
+`DupMapKeyEnforcedAPF` enforces detection and rejection of duplidate map keys. Decoding stops immediately and returns `DupMapKeyError` when the first duplicate key is detected. The error includes the duplicate map key and the index number. 
+
+APF suffix means "Allow Partial Fill" so the destination map or struct can contain some decoded values at the time of error. It is the caller's responsibility to respond to the `DupMapKeyError` by discarding the partially filled result if that's required by their protocol.
+
+</details>
+
+<details>
+ <summary>Tag Validity</summary><p>
+
+This library checks tag validity for built-in tags (currently tag numbers 0, 1, 2, 3, and 55799):
+
+* Inadmissible type for tag content 
+* Inadmissible value for tag content
+
+Unknown tag data items (not tag number 0, 1, 2, 3, or 55799) are handled in two ways:
+
+* When decoding into an empty interface, unknown tag data item will be decoded into `cbor.Tag` data type, which contains tag number and tag content.  The tag content will be decoded into the default Go data type for the CBOR data type.
+* When decoding into other Go types, unknown tag data item is decoded into the specified Go type.  If Go type is registered with a tag number, the tag number can optionally be verified.
+
+Decoder also has an option to forbid tag data items (treat any tag data item as error) which is specified by protocols such as CTAP2 Canonical CBOR.  
+
+For more information, see [decoding options](#decoding-options-1) and [tag options](#tag-options).
+
+</details>
+
+## Limitations
+
+If any of these limitations prevent you from using this library, please open an issue along with a link to your project.
+
+* CBOR `Undefined` (0xf7) value decodes to Go's `nil` value.  CBOR `Null` (0xf6) more closely matches Go's `nil`.
+* CBOR map keys with data types not supported by Go for map keys are ignored and an error is returned after continuing to decode remaining items.  
+* When decoding registered CBOR tag data to interface type, decoder creates a pointer to registered Go type matching CBOR tag number.  Requiring a pointer for this is a Go limitation. 
+
+## Fuzzing and Code Coverage
+
+__Code coverage__ is always 95% or higher (with `go test -cover`) when tagging a release.

+__Coverage-guided fuzzing__ must pass billions of execs using before tagging a release.  Fuzzing is done using nonpublic code which may eventually get merged into this project.  Until then, reports like OpenSSF&nbsp;Scorecard can't detect fuzz tests being used by this project.

+
+## Versions and API Changes
+This project uses [Semantic Versioning](https://semver.org), so the API is always backwards compatible unless the major version number changes.  
+
+These functions have signatures identical to encoding/json and their API will continue to match `encoding/json` even after major new releases:  
+`Marshal`, `Unmarshal`, `NewEncoder`, `NewDecoder`, `(*Encoder).Encode`, and `(*Decoder).Decode`.
+
+Exclusions from SemVer:
+- Newly added API documented as "subject to change".
+- Newly added API in the master branch that has never been tagged in non-beta release.
+- If function parameters are unchanged, bug fixes that change behavior (e.g. return error for edge case was missed in prior version).  We try to highlight these in the release notes and add extended beta period.  E.g. [v2.5.0-beta](https://github.com/fxamacker/cbor/releases/tag/v2.5.0-beta) (Dec 2022) -> [v2.5.0](https://github.com/fxamacker/cbor/releases/tag/v2.5.0) (Aug 2023).
+
+This project avoids breaking changes to behavior of encoding and decoding functions unless required to improve conformance with supported RFCs (e.g. RFC 8949, RFC 8742, etc.)  Visible changes that don't improve conformance to standards are typically made available as new opt-in settings or new functions.

+
+## Acknowledgements
+
+Many thanks to all the contributors on this project!
+
+I'm especially grateful to Bastian Müller and Dieter Shirley for suggesting and collaborating on CBOR stream mode, and much more.
+
+I'm very grateful to Stefan Tatschner, Yawning Angel, Jernej Kos, x448, ZenGround0, and Jakob Borg for their contributions or support in the very early days.
+
+Big thanks to Ben Luddy for his contributions in v2.6.0 and v2.7.0.
+
+This library clearly wouldn't be possible without Carsten Bormann authoring CBOR RFCs.
+
+Special thanks to Laurence Lundblade and Jeffrey Yasskin for their help on IETF mailing list or at [7049bis](https://github.com/cbor-wg/CBORbis).
+
+Huge thanks to The Go Authors for creating a fun and practical programming language with batteries included!
+
+This library uses `x448/float16` which used to be included.  As a standalone package, `x448/float16` is useful to other projects as well.

+Package cbor is a modern CBOR codec (RFC 8949 & RFC 7049) with CBOR tags,
+Go struct tags (toarray/keyasint/omitempty), Core Deterministic Encoding,
+CTAP2, Canonical CBOR, float64->32->16, and duplicate map key detection.
+
+Encoding options allow "preferred serialization" by encoding integers and floats
+to their smallest forms (e.g. float16) when values fit.
+
+Struct tags like "keyasint", "toarray" and "omitempty" make CBOR data smaller
+and easier to use with structs.
+
+For example, "toarray" tag makes struct fields encode to CBOR array elements.  And
+"keyasint" makes a field encode to an element of CBOR map with specified int key.
+
+Latest docs can be viewed at https://github.com/fxamacker/cbor#cbor-library-in-go
+
+# Basics
+
+The Quick Start guide is at https://github.com/fxamacker/cbor#quick-start
+
+Function signatures identical to encoding/json include:
+
+	Marshal, Unmarshal, NewEncoder, NewDecoder, (*Encoder).Encode, (*Decoder).Decode.
+
+Standard interfaces include:
+
+	BinaryMarshaler, BinaryUnmarshaler, Marshaler, and Unmarshaler.
+
+Custom encoding and decoding is possible by implementing standard interfaces for
+user-defined Go types.
+
+Codec functions are available at package-level (using defaults options) or by
+creating modes from options at runtime.
+
+"Mode" in this API means definite way of encoding (EncMode) or decoding (DecMode).
+
+EncMode and DecMode interfaces are created from EncOptions or DecOptions structs.
+
+	em, err := cbor.EncOptions{...}.EncMode()
+	em, err := cbor.CanonicalEncOptions().EncMode()
+	em, err := cbor.CTAP2EncOptions().EncMode()
+
+Modes use immutable options to avoid side-effects and simplify concurrency. Behavior of
+modes won't accidentally change at runtime after they're created.
+
+Modes are intended to be reused and are safe for concurrent use.
+
+EncMode and DecMode Interfaces
+
+	    // EncMode interface uses immutable options and is safe for concurrent use.
+	    type EncMode interface {
+		Marshal(v interface{}) ([]byte, error)
+		NewEncoder(w io.Writer) *Encoder
+		EncOptions() EncOptions  // returns copy of options
+	    }
+
+	    // DecMode interface uses immutable options and is safe for concurrent use.
+	    type DecMode interface {
+		Unmarshal(data []byte, v interface{}) error
+		NewDecoder(r io.Reader) *Decoder
+		DecOptions() DecOptions  // returns copy of options
+	    }
+
+Using Default Encoding Mode
+
+	b, err := cbor.Marshal(v)
+
+	encoder := cbor.NewEncoder(w)
+	err = encoder.Encode(v)
+
+Using Default Decoding Mode
+
+	err := cbor.Unmarshal(b, &v)
+
+	decoder := cbor.NewDecoder(r)
+	err = decoder.Decode(&v)
+
+Creating and Using Encoding Modes
+
+	// Create EncOptions using either struct literal or a function.
+	opts := cbor.CanonicalEncOptions()
+
+	// If needed, modify encoding options
+	opts.Time = cbor.TimeUnix
+
+	// Create reusable EncMode interface with immutable options, safe for concurrent use.
+	em, err := opts.EncMode()
+
+	// Use EncMode like encoding/json, with same function signatures.
+	b, err := em.Marshal(v)
+	// or
+	encoder := em.NewEncoder(w)
+	err := encoder.Encode(v)
+
+	// NOTE: Both em.Marshal(v) and encoder.Encode(v) use encoding options
+	// specified during creation of em (encoding mode).
+
+# CBOR Options
+
+Predefined Encoding Options: https://github.com/fxamacker/cbor#predefined-encoding-options
+
+Encoding Options: https://github.com/fxamacker/cbor#encoding-options
+
+Decoding Options: https://github.com/fxamacker/cbor#decoding-options
+
+# Struct Tags
+
+Struct tags like `cbor:"name,omitempty"` and `json:"name,omitempty"` work as expected.
+If both struct tags are specified then `cbor` is used.
+
+Struct tags like "keyasint", "toarray", and "omitempty" make it easy to use
+very compact formats like COSE and CWT (CBOR Web Tokens) with structs.
+
+For example, "toarray" makes struct fields encode to array elements.  And "keyasint"
+makes struct fields encode to elements of CBOR map with int keys.
+
+https://raw.githubusercontent.com/fxamacker/images/master/cbor/v2.0.0/cbor_easy_api.png
+
+Struct tags are listed at https://github.com/fxamacker/cbor#struct-tags-1
+
+# Tests and Fuzzing
+
+Over 375 tests are included in this package. Cover-guided fuzzing is handled by
+a private fuzzer that replaced fxamacker/cbor-fuzz years ago.
