"""Symmetric- and asymmetric-key encryption algorithms.

Encryption algorithms transform plaintext in some way that
is dependent on a key or key pair, producing ciphertext.

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``.
