## 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.

## SEE ALSO

## HISTORY

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