<h1><a name="description">DESCRIPTION</a></h1>
|
|
<p>All of the functions described on this page are deprecated.
|
|
Applications should instead use EVP PKEY APIs.</p>
|
|
<p>RSA_sign_ASN1_OCTET_STRING() signs the octet string <strong>m</strong> of size
|
|
<strong>m_len</strong> using the private key <strong>rsa</strong> represented in DER using PKCS #1
|
|
padding. It stores the signature in <strong>sigret</strong> and the signature size
|
|
in <strong>siglen</strong>. <strong>sigret</strong> must point to <strong>RSA_size(rsa)</strong> bytes of
|
|
memory.</p>
|
|
<p><strong>dummy</strong> is ignored.</p>
|
|
<p>The random number generator must be seeded when calling
|
|
RSA_sign_ASN1_OCTET_STRING().
|
|
If the automatic seeding or reseeding of the OpenSSL CSPRNG fails due to
|
|
external circumstances (see <em>RAND(7)</em>), the operation will fail.</p>
|
|
<p>RSA_verify_ASN1_OCTET_STRING() verifies that the signature <strong>sigbuf</strong>
|
|
of size <strong>siglen</strong> is the DER representation of a given octet string
|
|
<strong>m</strong> of size <strong>m_len</strong>. <strong>dummy</strong> is ignored. <strong>rsa</strong> is the signer's
|
|
public key.</p>

<h1><a name="return_values">RETURN VALUES</a></h1>
|
|
<p>RSA_sign_ASN1_OCTET_STRING() returns 1 on success, 0 otherwise.
|
|
RSA_verify_ASN1_OCTET_STRING() returns 1 on successful verification, 0
|
|
otherwise.</p>
|
|
<p>The error codes can be obtained by <em>ERR_get_error(3)</em>.</p>
