ucryptolib – cryptographic ciphers¶
__init__(key, mode[, IV])¶
Initialize cipher object, suitable for encryption/decryption. Note: after initialization, cipher object can be use only either for encryption or decryption. Running decrypt() operation after encrypt() or vice versa is not supported.
key is an encryption/decryption key (bytes-like).
ucryptolib.MODE_ECBif it exists) for Electronic Code Book (ECB).
ucryptolib.MODE_CBCif it exists) for Cipher Block Chaining (CBC)
IV is an initialization vector for CBC mode.
Encrypt in_buf. If no out_buf is given result is returned as a newly allocated
bytesobject. Otherwise, result is written into mutable buffer out_buf. in_buf and out_buf can also refer to the same mutable buffer, in which case data is encrypted in-place.
