Welcome to PEP272 Encryption’s documentation!¶
To prevent reinventing the wheel while creating a PEP-272 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 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+.'
Structure¶
This documentation is structured.
It starts with the Installation instructions. The second chapter is Tutorial, giving a quick example without explaining too much. The How-To gives practical solutions to common problems. Look up in the Library reference. The Discussions section explains in-depth knowledge of topics important in the context of the library to get a deeper understanding of the software.
