Default Params with a specified hash function
OAEP encryption
:: HashAlgorithm hash | |
=> ByteString | Seed |
-> OAEPParams hash ByteString ByteString | 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.
:: (HashAlgorithm hash, MonadRandom m) | |
=> OAEPParams hash ByteString ByteString | OAEP params to use for encryption. |
-> PublicKey | Public key. |
-> ByteString | Message to encrypt |
-> m (Either Error ByteString) |
Encrypt a message using OAEP
OAEP decryption
:: HashAlgorithm hash | |
=> Maybe Blinder | Optional blinder |
-> OAEPParams hash ByteString ByteString | 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
:: (HashAlgorithm hash, MonadRandom m) | |
=> OAEPParams hash ByteString ByteString | OAEP params to use for decryption |
-> PrivateKey | Private key |
-> ByteString | Cipher text |
-> m (Either Error ByteString) |
Decrypt a ciphertext using OAEP and by automatically generating a blinder.
