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

<p>X509_CRL_get0_by_serial() attempts to find a revoked entry in <i>crl</i> for serial number <i>serial</i>. If it is successful, it sets <i>*ret</i> to the internal pointer of the matching entry. As a result, <i>*ret</i> <b>MUST NOT</b> be freed after the call.</p>

<p>X509_CRL_get0_by_cert() is similar to X509_get0_by_serial() except it looks for a revoked entry using the serial number of certificate <i>x</i>.</p>

<p>X509_CRL_get_REVOKED() returns an internal pointer to a STACK of all revoked entries for <i>crl</i>.</p>

<p>X509_REVOKED_get0_serialNumber() returns an internal pointer to the serial number of <i>r</i>.</p>

<p>X509_REVOKED_get0_revocationDate() returns an internal pointer to the revocation date of <i>r</i>.</p>

<p>X509_REVOKED_set_serialNumber() sets the serial number of <i>r</i> to <i>serial</i>. The supplied <i>serial</i> pointer is not used internally so it should be freed after use.</p>

<p>X509_REVOKED_set_revocationDate() sets the revocation date of <i>r</i> to <i>tm</i>. The supplied <i>tm</i> pointer is not used internally so it should be freed after use.</p>

<p>X509_CRL_add0_revoked() appends revoked entry <i>rev</i> to CRL <i>crl</i>. The pointer <i>rev</i> is used internally so it <b>MUST NOT</b> be freed after the call: it is freed when the parent CRL is freed.</p>

<p>X509_CRL_sort() sorts the revoked entries of <i>crl</i> into ascending serial number order.</p>

<h1 id="NOTES">NOTES</h1>

<p>Applications can determine the number of revoked entries returned by X509_CRL_get_REVOKED() using sk_X509_REVOKED_num() and examine each one in turn using sk_X509_REVOKED_value().</p>

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

<p>X509_CRL_get0_by_serial() and X509_CRL_get0_by_cert() return 0 for failure, 1 on success except if the revoked entry has the reason <code>removeFromCRL</code> (8), in which case 2 is returned.</p>

<p>X509_CRL_get_REVOKED() returns a STACK of revoked entries.</p>

<p>X509_REVOKED_get0_serialNumber() returns an <b>ASN1_INTEGER</b> structure.</p>

<p>X509_REVOKED_get0_revocationDate() returns an <b>ASN1_TIME</b> structure.</p>

<p>X509_REVOKED_set_serialNumber(), X509_REVOKED_set_revocationDate(), X509_CRL_add0_revoked() and X509_CRL_sort() return 1 for success and 0 for failure.</p>
