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.
GCRY_CIPHER_3DES
Triple-DES with 3 keys as EDE. The key size of this algorithm is 168 bits 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 supported key sizes are 8 to 576 bits in 8 bit increments.
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_RIJNDAEL192
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 bits 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.
GCRY_CIPHER_SERPENT128
GCRY_CIPHER_SERPENT192
GCRY_CIPHER_SERPENT256
The Serpent cipher from the AES contest.
GCRY_CIPHER_RFC2268_40
GCRY_CIPHER_RFC2268_128
Ron’s Cipher 2 in the 40 and 128 bit variants.
GCRY_CIPHER_SEED
A 128 bit cipher as described by RFC4269.
GCRY_CIPHER_CAMELLIA128
GCRY_CIPHER_CAMELLIA192
GCRY_CIPHER_CAMELLIA256
The Camellia cipher by NTT. See http://info.isl.ntt.co.jp/crypt/eng/camellia/specifications.html.
GCRY_CIPHER_SALSA20
This is the Salsa20 stream cipher.
GCRY_CIPHER_SALSA20R12
This is the Salsa20/12 - reduced round version of Salsa20 stream cipher.
GCRY_CIPHER_GOST28147
The GOST 28147-89 cipher, defined in the respective GOST standard. Translation of this GOST into English is provided in the RFC-5830.
GCRY_CIPHER_GOST28147_MESH
The GOST 28147-89 cipher, defined in the respective GOST standard. Translation of this GOST into English is provided in the RFC-5830. This cipher will use CryptoPro keymeshing as defined in RFC 4357 if it has to be used for the selected parameter set.
GCRY_CIPHER_CHACHA20
This is the ChaCha20 stream cipher.
GCRY_CIPHER_SM4
A 128 bit cipher by the State Cryptography Administration of China (SCA). See https://tools.ietf.org/html/draft-ribose-cfrg-sm4-10.
