NAME

EVP_rc5_32_12_16_cbc, EVP_rc5_32_12_16_cfb, EVP_rc5_32_12_16_cfb64, EVP_rc5_32_12_16_ecb, EVP_rc5_32_12_16_ofb - EVP RC5 cipher

SYNOPSIS

 #include <openssl/evp.h>

 const EVP_CIPHER *EVP_rc5_32_12_16_cbc(void)
 const EVP_CIPHER *EVP_rc5_32_12_16_cfb(void)
 const EVP_CIPHER *EVP_rc5_32_12_16_cfb64(void)
 const EVP_CIPHER *EVP_rc5_32_12_16_ecb(void)
 const EVP_CIPHER *EVP_rc5_32_12_16_ofb(void)

DESCRIPTION

The RC5 encryption algorithm for EVP.

EVP_rc5_32_12_16_cbc(), EVP_rc5_32_12_16_cfb(), EVP_rc5_32_12_16_cfb64(), EVP_rc5_32_12_16_ecb(), EVP_rc5_32_12_16_ofb()

RC5 encryption algorithm in CBC, CFB, ECB and OFB modes respectively. This is a variable key length cipher with an additional "number of rounds" parameter. By default the key length is set to 128 bits and 12 rounds.

RETURN VALUES

These functions return an EVP_CIPHER structure that contains the implementation of the symmetric cipher. See EVP_CIPHER_meth_new(3) for details of the EVP_CIPHER structure.

BUGS

Currently the number of rounds in RC5 can only be set to 8, 12 or 16. This is a limitation of the current RC5 code rather than the EVP interface.
