DESCRIPTION

These functions provide the Camellia encryption algorithm in the evp(3) framework. 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.

EVP_camellia_128_cfb(), EVP_camellia_192_cfb(), and EVP_camellia_256_cfb() are aliases for EVP_camellia_128_cfb128(), EVP_camellia_192_cfb128(), and EVP_camellia_256_cfb128(), implemented as macros.

RETURN VALUES

These functions return an EVP_CIPHER structure that provides the implementation of the symmetric cipher.

HISTORY

These functions first appeared in OpenSSL 0.9.8c and have been available since OpenBSD 4.5.
