padding and unpadding
pad :: CPRG g => g -> Int -> ByteString -> Either Error (ByteString, g)Source
This produce a standard PKCS1.5 padding for encryption
padSignature :: Int -> ByteString -> Either Error ByteStringSource
Produce a standard PKCS1.5 padding for signature
unpad :: ByteString -> Either Error ByteStringSource
Try to remove a standard PKCS1.5 encryption padding.
private key operations
Arguments
| :: Maybe Blinder | optional blinder |
| -> PrivateKey | RSA private key |
| -> ByteString | cipher 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
Arguments
| :: CPRG g | |
| => g | random generator |
| -> PrivateKey | RSA private key |
| -> ByteString | cipher text |
| -> (Either Error ByteString, g) |
decrypt message using the private key and by automatically generating a blinder.
Arguments
| :: Maybe Blinder | optional blinder |
| -> HashDescr | hash descriptor |
| -> PrivateKey | private key |
| -> ByteString | message 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
Arguments
| :: CPRG g | |
| => g | random generator |
| -> HashDescr | Hash descriptor |
| -> PrivateKey | private key |
| -> ByteString | message to sign |
| -> (Either Error ByteString, g) |
sign message using the private key and by automatically generating a blinder.
public key operations
encrypt :: CPRG g => g -> PublicKey -> ByteString -> (Either Error ByteString, g)Source
encrypt a bytestring using the public key and a CPRG random generator.
the message need to be smaller than the key size - 11
verify :: HashDescr -> PublicKey -> ByteString -> ByteString -> BoolSource
verify message with the signed message
