Documentation <https://pep272-encryption.readthedocs.io/en/latest/>_

To prevent reinventing the wheel while creating a PEP-272 <https://www.python.org/dev/peps/pep-0272/>_ interface for a new block cipher encryption, this library aims to create an extensible framework for new libraries.

Currently following modes of operation are supported:

• ECB
• CBC
• CFB
• OFB
• CTR

The PGP mode of operation <https://tools.ietf.org/html/rfc4880#section-13.9>_ is not supported. It may be added in the future.

Example

In this example encrypt_aes(key, block) will encrypt one block of AES while decrypt_aes(key, block) will decrypt one.

from pep272_encryption import PEP272Cipher, MODE_ECB class AESCipher: ... """ ... PEP-272 cipher class for AES ... """ ... block_size = 16 ... ... def encrypt_block(self, key, block, **kwargs): ... return encrypt_aes(key, block) ...
... def decrypt_block(self, key, block, **kwargs): ... return decrypt_aes(key, block) ...
cipher = AESCipher(b'\00'*16, MODE_ECB) cipher.encrypt(b'\00'*16) b'f\xe9K\xd4\xef\x8a,;\x88L\xfaY\xca4+.'
