defaultOAEPParams :: HashFunction -> OAEPParams Source
Default Params with a specified hash function
OAEP encryption
Arguments
| :: ByteString | Seed |
| -> OAEPParams | OAEP params to use for encryption |
| -> PublicKey | Public key. |
| -> ByteString | Message to encrypt |
| -> Either Error ByteString |
Encrypt a message using OAEP with a predefined seed.
Arguments
| :: CPRG g | |
| => g | random number generator. |
| -> OAEPParams | OAEP params to use for encryption. |
| -> PublicKey | Public key. |
| -> ByteString | Message to encrypt |
| -> (Either Error ByteString, g) |
Encrypt a message using OAEP
OAEP decryption
Arguments
| :: Maybe Blinder | Optional blinder |
| -> OAEPParams | OAEP params to use for decryption |
| -> PrivateKey | Private key |
| -> ByteString | Cipher 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
Arguments
| :: CPRG g | |
| => g | random number generator |
| -> OAEPParams | OAEP params to use for decryption |
| -> PrivateKey | Private key |
| -> ByteString | Cipher text |
| -> (Either Error ByteString, g) |
Decrypt a ciphertext using OAEP and by automatically generating a blinder.
