# Documentation

data Error #

error possible during encryption, decryption or signing.

Constructors

MessageSizeIncorrect | the message to decrypt is not of the correct size (need to be == private_size)
MessageTooLong | the message to encrypt is too long
MessageNotRecognized | the message decrypted doesn't have a PKCS15 structure (0 2 .. 0 msg)
SignatureTooLong | the message's digest is too long
InvalidParameters | some parameters lead to breaking assumptions.

data PrivateKey #

Represent a RSA private key.

Only the pub, d fields are mandatory to fill.

p, q, dP, dQ, qinv are by-product during RSA generation, but are useful to record here to speed up massively the decrypt and sign operation.

implementations can leave optional fields to 0.
