Padding and unpadding
Produce a standard PKCS1.5 padding for signature
Try to remove a standard PKCS1.5 encryption padding.
Private key operations
value
decrypt :: Maybe Blinderoptional blinder
-> PrivateKeyRSA private key
-> ByteStringcipher text
-> Either Error ByteString
decrypt message using the private key.
When the decryption is not in a context where an attacker could gain information from the timing of the operation, the blinder can be set to None.
If unsure always set a blinder or use decryptSafer
The message is returned un-padded.
value
decryptSafer :: MonadRandom m=> PrivateKeyRSA private key
-> ByteStringcipher text
-> m (Either Error ByteString)
decrypt message using the private key and by automatically generating a blinder.
value
sign :: HashAlgorithmASN1 hashAlg=> Maybe Blinderoptional blinder
-> Maybe hashAlghash algorithm
-> PrivateKeyprivate key
-> ByteStringmessage to sign
-> Either Error ByteString
sign message using private key, a hash and its ASN1 description
When the signature is not in a context where an attacker could gain information from the timing of the operation, the blinder can be set to None.
If unsure always set a blinder or use signSafer
value
signSafer :: (HashAlgorithmASN1 hashAlg, MonadRandom m)=> Maybe hashAlgHash algorithm
-> PrivateKeyprivate key
-> ByteStringmessage to sign
-> m (Either Error ByteString)
sign message using the private key and by automatically generating a blinder.
Public key operations
encrypt a bytestring using the public key.
The message needs to be smaller than the key size - 11. The message should not be padded.
verify message with the signed message
Hash ASN1 description
A specialized class for hash algorithm that can product a ASN1 wrapped description the algorithm plus the content of the digest.
