DESCRIPTION

21       The RC2 encryption algorithm for EVP.
22
23       EVP_rc2_cbc(), EVP_rc2_cfb(), EVP_rc2_cfb64(), EVP_rc2_ecb(),
24       EVP_rc2_ofb()
25           RC2 encryption algorithm in CBC, CFB, ECB and OFB modes
26           respectively. This is a variable key length cipher with an
27           additional parameter called "effective key bits" or "effective key
28           length". By default both are set to 128 bits.
29
30       EVP_rc2_40_cbc(), EVP_rc2_64_cbc()
31           RC2 algorithm in CBC mode with a default key length and effective
32           key length of 40 and 64 bits.
33
34           WARNING: these functions are obsolete. Their usage should be
35           replaced with the EVP_rc2_cbc(), EVP_CIPHER_CTX_set_key_length()
36           and EVP_CIPHER_CTX_ctrl() functions to set the key length and
37           effective key length.
38

RETURN VALUES

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