PKCS v1.5-padded operations, as defined by PKCS #1 v1.5.
Keys must have a minimum of
11 + len(message) bytes.
sig_encode mask key message is the PKCS1-padded (type 1)
message signed by the
key. Note that this operation performs only the padding and RSA transformation steps of the PKCS 1.5 signature.
sig_decode key signature is either
Some message if the
signature was produced with the given
key as per sign, or
encrypt g key message is a PKCS1-padded (type 2) and encrypted
