<p>The RC2 encryption algorithm for EVP.</p>
<dl>
<dt id="EVP_rc2_cbc-EVP_rc2_cfb-EVP_rc2_cfb64-EVP_rc2_ecb-EVP_rc2_ofb">EVP_rc2_cbc(), EVP_rc2_cfb(), EVP_rc2_cfb64(), EVP_rc2_ecb(), EVP_rc2_ofb()</dt>
<dd>
<p>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.</p>
</dd>
<dt id="EVP_rc2_40_cbc-EVP_rc2_64_cbc">EVP_rc2_40_cbc(), EVP_rc2_64_cbc()</dt>
<dd>
<p>RC2 algorithm in CBC mode with a default key length and effective key length of 40 and 64 bits.</p>
<p>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.</p>
</dd>

<p>These functions return an <b>EVP_CIPHER</b> structure that contains the implementation of the symmetric cipher. See <a href="../man3/EVP_CIPHER_meth_new.html">EVP_CIPHER_meth_new(3)</a> for details of the <b>EVP_CIPHER</b> structure.</p>
