data OAEPParams hash seed output Source #

Parameters for OAEP encryption/decryption

Constructors

OAEPParams
Fields oaepHash :: hash Hash function to use. oaepMaskGenAlg :: MaskGenAlgorithm seed output Mask Gen algorithm to use. oaepLabel :: Maybe ByteString Optional label prepended to message.

Default Params with a specified hash function

OAEP encryption

Arguments

:: 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.

Arguments

:: ( 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

Arguments

:: 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

Arguments

:: ( 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.
