// Signatures in PKCS1v15 must match the key's modulus in
// length. However with SSH, some signers provide RSA
// signatures which are missing the MSB 0's of the bignum
// represented. With ssh-rsa signatures, this is encouraged by
// the spec (even though e.g. OpenSSH will give the full
// length unconditionally). With rsa-sha2-* signatures, the
// verifier is allowed to support these, even though they are
// out of spec. See RFC 4253 Section 6.6 for ssh-rsa and RFC
// 8332 Section 3 for rsa-sha2-* details.
//
// In practice:
// * OpenSSH always allows "short" signatures:
// https://github.com/openssh/openssh-portable/blob/V_9_8_P1/ssh-rsa.c#L526
// but always generates padded signatures:
// https://github.com/openssh/openssh-portable/blob/V_9_8_P1/ssh-rsa.c#L439
//
// * PuTTY versions 0.81 and earlier will generate short
// signatures for all RSA signature variants. Note that
// PuTTY is embedded in other software, such as WinSCP and
// FileZilla. At the time of writing, a patch has been
// applied to PuTTY to generate padded signatures for
// rsa-sha2-*, but not yet released:
// https://git.tartarus.org/?p=simon/putty.git;a=commitdiff;h=a5bcf3d384e1bf15a51a6923c3724cbbee022d8e
//
// * SSH.NET versions 2024.0.0 and earlier will generate short
// signatures for all RSA signature variants, fixed in 2024.1.0:
// https://github.com/sshnet/SSH.NET/releases/tag/2024.1.0
//
// As a result, we pad these up to the key size by inserting
// leading 0's.
//
// Note that support for short signatures with rsa-sha2-* may
// be removed in the future due to such signatures not being
// allowed by the spec.
