Constructor & Destructor Documentation

◆ DLIES_Encryptor() [1/2]

Botan::DLIES_Encryptor::DLIES_Encryptor ( const DH_PrivateKey own_priv_key,
RandomNumberGenerator rng,
KDF kdf,
MessageAuthenticationCode mac,
size_t  mac_key_len = 20 
)

Stream mode: use KDF to provide a stream of bytes to xor with the message

Parameters
own_priv_keyown (ephemeral) DH private key
rngthe RNG to use
kdfthe KDF that should be used
macthe MAC function that should be used
mac_key_lenkey length of the MAC function. Default = 20 bytes

output = (ephemeral) public key + ciphertext + tag
