# SYNOPSIS

     #include <openssl/evp.h>

# DESCRIPTION

The RC2 encryption algorithm for EVP.

EVP_rc2_cbc(), EVP_rc2_cfb(), EVP_rc2_cfb64(), EVP_rc2_ecb(), EVP_rc2_ofb()
  RC2 encryption algorithm in CBC, CFB, ECB and OFB modes respectively. This is a variable key length cipher with an additional parameter called "effective key bits" or "effective key length". By default both are set to 128 bits.
EVP_rc2_40_cbc(), EVP_rc2_64_cbc()
  RC2 algorithm in CBC mode with a default key length and effective key length of 40 and 64 bits.

  WARNING: these functions are obsolete. Their usage should be replaced with the EVP_rc2_cbc(), EVP_CIPHER_CTX_set_key_length() and EVP_CIPHER_CTX_ctrl() functions to set the key length and effective key length.

# 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.
