Symmetric algorithms -------------------- Encryption can easily be reversed, if (and, hopefully, only if) one knows the same key. In other words, sender and receiver share the same key. The symmetric encryption modules here all support the interface described in PEP 272, "API for Block Encryption Algorithms". If you don't know which algorithm to choose, use AES because it's standard and has undergone a fair bit of examination. ======================== ======= ======================== Module name Type Description ======================== ======= ======================== `Crypto.Cipher.AES` Block Advanced Encryption Standard `Crypto.Cipher.ARC2` Block Alleged RC2 `Crypto.Cipher.ARC4` Stream Alleged RC4 `Crypto.Cipher.Blowfish` Block Blowfish `Crypto.Cipher.CAST` Block CAST `Crypto.Cipher.DES` Block The Data Encryption Standard. Very commonly used in the past, but today its 56-bit keys are too small. `Crypto.Cipher.DES3` Block Triple DES. `Crypto.Cipher.XOR` Stream The simple XOR cipher. ======================== ======= ======================== Asymmetric algorithms --------------------- For asymmetric algorithms, the key to be used for decryption is totally different and cannot be derived in a feasible way from the key used for encryption. Put differently, sender and receiver each own one half of a key pair. The encryption key is often called ``public`` whereas the decryption key is called ``private``. ========================== ======================= Module name Description ========================== ======================= `Crypto.Cipher.PKCS1_v1_5` PKCS#1 v1.5 encryption, based on RSA key pairs `Crypto.Cipher.PKCS1_OAEP` PKCS#1 OAEP encryption, based on RSA key pairs ========================== ======================= :undocumented: __revision__, __package__, _AES, _ARC2, _ARC4, _Blowfish _CAST, _DES, _DES3, _XOR ZAESZARC2ZARC4ZBlowfishZCASTZDESZDES3ZXORZ PKCS1_v1_5Z PKCS1_OAEPz$Id$N)�__doc__�__all__Z__revision__��r���r����I/opt/alt/python37/lib64/python3.7/site-packages/Crypto/Cipher/__init__.py�<module>I���s ���
