<p>EVP_PKEY_CTX_set1_pbe_pass
- generic KDF support functions</p>
<p>
</p>
<hr />
<h1><a name="synopsis">SYNOPSIS</a></h1>
<pre>
#include <openssl/kdf.h></pre>
<pre>
int EVP_PKEY_CTX_set1_pbe_pass(EVP_PKEY_CTX *pctx, unsigned char *pass,
int passlen);</pre>
<p>
</p>
<hr />
<h1><a name="description">DESCRIPTION</a></h1>
<p>These functions are generic support functions for all KDF algorithms.</p>
<p>EVP_PKEY_CTX_set1_pbe_pass() sets the password to the <strong>passlen</strong> first
bytes from <strong>pass</strong>.</p>
<p>
</p>
<hr />
<h1><a name="string_ctrls">STRING CTRLS</a></h1>
<p>There is also support for string based control operations via
<em>EVP_PKEY_CTX_ctrl_str(3)</em>.
The <strong>password</strong> can be directly specified using the <strong>type</strong> parameter
"pass" or given in hex encoding using the "hexpass" parameter.</p>
<p>
</p>
<hr />
<h1><a name="notes">NOTES</a></h1>
<p>All these functions are implemented as macros.</p>
<p>
</p>
<hr />
<h1><a name="return_values">RETURN VALUES</a></h1>
<p>All these functions return 1 for success and 0 or a negative value for failure.
In particular a return value of -2 indicates the operation is not supported by
the public key algorithm.</p>
