Symmetric Key Algorithms

Symmetric key algorithms are encryption algorithms that use the same cryptographic keys for both encryption and decryption of data. This operation is also known as Symmetric Key Encryption.

wolfcrypt provides access to the following Symmetric Key Ciphers:

Example

>>> from wolfcrypt.ciphers import Aes, MODE_CBC
>>>
>>> cipher = Aes(b'0123456789abcdef', MODE_CBC, b'1234567890abcdef')
>>> ciphertext = cipher.encrypt('now is the time ')
>>> ciphertext
b'\x95\x94\x92W_B\x81S,\xcc\x9dFw\xa23\xcb'
>>> cipher.decrypt(ciphertext)
b'now is the time '
