Default Params with a specified hash function
OAEP encryption
value
encryptWithSeed :: HashAlgorithm hash=> ByteStringSeed
-> OAEPParams hash ByteString ByteStringOAEP params to use for encryption
-> PublicKeyPublic key.
-> ByteStringMessage to encrypt
-> Either Error ByteString
Encrypt a message using OAEP with a predefined seed.
value
encrypt :: (HashAlgorithm hash, MonadRandom m)=> OAEPParams hash ByteString ByteStringOAEP params to use for encryption.
-> PublicKeyPublic key.
-> ByteStringMessage to encrypt
-> m (Either Error ByteString)
Encrypt a message using OAEP
OAEP decryption
value
decrypt :: HashAlgorithm hash=> Maybe BlinderOptional blinder
-> OAEPParams hash ByteString ByteStringOAEP params to use for decryption
-> PrivateKeyPrivate key
-> ByteStringCipher text
-> Either Error ByteString
Decrypt a ciphertext using OAEP
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 decryptSafer
value
decryptSafer :: (HashAlgorithm hash, MonadRandom m)=> OAEPParams hash ByteString ByteStringOAEP params to use for decryption
-> PrivateKeyPrivate key
-> ByteStringCipher text
-> m (Either Error ByteString)
Decrypt a ciphertext using OAEP and by automatically generating a blinder.
