<p>RSA_sign, RSA_verify - RSA signatures</p>

<h1 id="SYNOPSIS">SYNOPSIS</h1>

<pre><code> #include &lt;openssl/rsa.h&gt;

 int RSA_sign(int type, const unsigned char *m, unsigned int m_len,
              unsigned char *sigret, unsigned int *siglen, RSA *rsa);

 int RSA_verify(int type, const unsigned char *m, unsigned int m_len,
                unsigned char *sigbuf, unsigned int siglen, RSA *rsa);</code></pre>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>RSA_sign() signs the message digest <b>m</b> of size <b>m_len</b> using the private key <b>rsa</b> using RSASSA-PKCS1-v1_5 as specified in RFC 3447. It stores the signature in <b>sigret</b> and the signature size in <b>siglen</b>. <b>sigret</b> must point to RSA_size(<b>rsa</b>) bytes of memory. Note that PKCS #1 adds meta-data, placing limits on the size of the key that can be used. See <a href="../man3/RSA_private_encrypt.html">RSA_private_encrypt(3)</a> for lower-level operations.</p>

<p><b>type</b> denotes the message digest algorithm that was used to generate <b>m</b>. If <b>type</b> is <b>NID_md5_sha1</b>, an SSL signature (MD5 and SHA1 message digests with PKCS #1 padding and no algorithm identifier) is created.</p>

<p>RSA_verify() verifies that the signature <b>sigbuf</b> of size <b>siglen</b> matches a given message digest <b>m</b> of size <b>m_len</b>. <b>type</b> denotes the message digest algorithm that was used to generate the signature. <b>rsa</b> is the signer&#39;s public key.</p>

<h1 id="RETURN-VALUES">RETURN VALUES</h1>

<p>RSA_sign() returns 1 on success. RSA_verify() returns 1 on successful verification.</p>

<p>The error codes can be obtained by <a href="../man3/ERR_get_error.html">ERR_get_error(3)</a>.</p>
