NAME

       EVP_rc2_cbc, EVP_rc2_cfb, EVP_rc2_cfb64, EVP_rc2_ecb, EVP_rc2_ofb, EVP_rc2_40_cbc,
       EVP_rc2_64_cbc - EVP RC2 cipher

SYNOPSIS

        #include <openssl/evp.h>

        const EVP_CIPHER *EVP_rc2_cbc(void)
        const EVP_CIPHER *EVP_rc2_cfb(void)
        const EVP_CIPHER *EVP_rc2_cfb64(void)
        const EVP_CIPHER *EVP_rc2_ecb(void)
        const EVP_CIPHER *EVP_rc2_ofb(void)
        const EVP_CIPHER *EVP_rc2_40_cbc(void)
        const EVP_CIPHER *EVP_rc2_64_cbc(void)

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.
