- =head1 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);
- =head1 DESCRIPTION
- The RC2 encryption algorithm for EVP.
- =over 4
- =item 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.
- =item 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.

- =head1 RETURN VALUES
- These functions return an B<EVP_CIPHER> structure that contains the
- implementation of the symmetric cipher. See L<EVP_CIPHER_meth_new(3)> for
- details of the B<EVP_CIPHER> structure.
