Available ciphers
=================
`GCRY_CIPHER_NONE'
This is not a real algorithm but used by some functions as error
return. The value always evaluates to false.
`GCRY_CIPHER_IDEA'
This is the IDEA algorithm. The constant is provided but there is
currently no implementation for it because the algorithm is
patented.
`GCRY_CIPHER_3DES'
Triple-DES with 3 Keys as EDE. The key size of this algorithm is
168 but you have to pass 192 bits because the most significant
bits of each byte are ignored.
`GCRY_CIPHER_CAST5'
CAST128-5 block cipher algorithm. The key size is 128 bits.
`GCRY_CIPHER_BLOWFISH'
The blowfish algorithm. The current implementation allows only for
a key size of 128 bits.
`GCRY_CIPHER_SAFER_SK128'
Reserved and not currently implemented.
`GCRY_CIPHER_DES_SK'
Reserved and not currently implemented.
`GCRY_CIPHER_AES'
`GCRY_CIPHER_AES128'
`GCRY_CIPHER_RIJNDAEL'
`GCRY_CIPHER_RIJNDAEL128'
AES (Rijndael) with a 128 bit key.
`GCRY_CIPHER_AES192'
`GCRY_CIPHER_RIJNDAEL128'
AES (Rijndael) with a 192 bit key.
`GCRY_CIPHER_AES256'
`GCRY_CIPHER_RIJNDAEL256'
AES (Rijndael) with a 256 bit key.
`GCRY_CIPHER_TWOFISH'
The Twofish algorithm with a 256 bit key.
`GCRY_CIPHER_TWOFISH128'
The Twofish algorithm with a 128 bit key.
`GCRY_CIPHER_ARCFOUR'
An algorithm which is 100% compatible with RSA Inc.'s RC4
algorithm. Note that this is a stream cipher and must be used
very carefully to avoid a couple of weaknesses.
`GCRY_CIPHER_DES'
Standard DES with a 56 bit key. You need to pass 64 bit but the
high bits of each byte are ignored. Note, that this is a weak
algorithm which can be broken in reasonable time using a brute
force approach.
