Camellia is a block cipher operating on 128 bit blocks. These functions use 128, 192, and 256-bit keys in the following modes, respectively: CBC, CFB with 1-bit shift, CFB with 8-bit shift, CFB with 128-bit shift, ECB, and OFB. .Pp .Fn EVP_camellia_128_cfb , .Fn EVP_camellia_192_cfb , and .Fn EVP_camellia_256_cfb are aliases for .Fn EVP_camellia_128_cfb128 , .Fn EVP_camellia_192_cfb128 , and .Fn EVP_camellia_256_cfb128 , implemented as macros. .Sh RETURN VALUES These functions return an .Vt EVP_CIPHER structure that provides the implementation of the symmetric cipher. .Sh SEE ALSO .Xr evp 3 , .Xr EVP_EncryptInit 3 .Sh HISTORY These functions first appeared in OpenSSL 0.9.8c and have been available since .Ox 4.5 .
