The original SSH RFC 4253 explicitly disallows padding. This applies to ssh-rsa signatures. The updated SSH RFC 8332 which defines the SHA2 RSA signature variants explicitly calls out the existence of signers who produce short signatures and specifies that verifiers may allow this behavior. In practice, PuTTY 0.81 and prior versions, as well as SSH.NET prior to 2024.1.0 always generated short signatures. Furthermore, PuTTY is embedded in other software like WinSCP and FileZilla, which are updated on their own schedules as well. This leads to occasional unexplained login errors, when using RSA keys. OpenSSH server allows these short signatures for all RSA algorithms.
