<h1><a name="description">DESCRIPTION</a></h1>
|
|
<p>All of the functions described on this page are deprecated.
|
|
Applications should instead use <em>EVP_PKEY_sign_init(3)</em>, <em>EVP_PKEY_sign(3)</em>,
|
|
<em>EVP_PKEY_verify_init(3)</em> and <em>EVP_PKEY_verify(3)</em>.</p>
|
|
<p><code>RSA_sign()</code> signs the message digest <strong>m</strong> of size <strong>m_len</strong> using the
|
|
private key <strong>rsa</strong> using RSASSA-PKCS1-v1_5 as specified in <a href="http://www.ietf.org/rfc/rfc3447.txt" class="rfc">RFC 3447</a>. It
|
|
stores the signature in <strong>sigret</strong> and the signature size in <strong>siglen</strong>.
|
|
<strong>sigret</strong> must point to RSA_size(<strong>rsa</strong>) bytes of memory.
|
|
Note that PKCS #1 adds meta-data, placing limits on the size of the
|
|
key that can be used.
|
|
See <em>RSA_private_encrypt(3)</em> for lower-level
|
|
operations.</p>
|
|
<p><strong>type</strong> denotes the message digest algorithm that was used to generate
|
|
<strong>m</strong>.
|
|
If <strong>type</strong> is <strong>NID_md5_sha1</strong>,
|
|
an SSL signature (MD5 and SHA1 message digests with PKCS #1 padding
|
|
and no algorithm identifier) is created.</p>
|
|
<p><code>RSA_verify()</code> verifies that the signature <strong>sigbuf</strong> of size <strong>siglen</strong>
|
|
matches a given message digest <strong>m</strong> of size <strong>m_len</strong>. <strong>type</strong> denotes
|
|
the message digest algorithm that was used to generate the signature.
|
|
<strong>rsa</strong> is the signer's public key.</p>

<h1><a name="return_values">RETURN VALUES</a></h1>
|
|
<p><code>RSA_sign()</code> returns 1 on success.
|
|
<code>RSA_verify()</code> returns 1 on successful verification.</p>
|
|
<p>The error codes can be obtained by <em>ERR_get_error(3)</em>.</p>
