<p>CMS_add0_cert() and CMS_add1_cert() add certificate <i>cert</i> to <i>cms</i> unless it is already present. This is used by <a href="../man3/CMS_sign_ex.html">CMS_sign_ex(3)</a> and <a href="../man3/CMS_sign.html">CMS_sign(3)</a> and may be used before calling <a href="../man3/CMS_verify.html">CMS_verify(3)</a> to help chain building in certificate validation. As the 0 implies, CMS_add0_cert() adds <i>cert</i> internally to <i>cms</i> and on success it must not be freed up by the caller. In contrast, the caller of CMS_add1_cert() must free <i>cert</i>. <i>cms</i> must be of type signed data or (authenticated) enveloped data. For signed data, such a certificate can be used when signing or verifying to fill in the signer certificate or to provide an extra CA certificate that may be needed for chain building in certificate validation.</p>
|
||
|
|
|
||
|
|
<p>CMS_get1_certs() returns all certificates in <i>cms</i>.</p>
|
||
|
|
|
||
|
|
<p>CMS_add0_crl() and CMS_add1_crl() add CRL <i>crl</i> to <i>cms</i>. <i>cms</i> must be of type signed data or (authenticated) enveloped data. For signed data, such a CRL may be used in certificate validation with <a href="../man3/CMS_verify.html">CMS_verify(3)</a>. It may be given both for inclusion when signing a CMS message and when verifying a signed CMS message.</p>
|
||
|
|
|
||
|
|
<p>CMS_get1_crls() returns all CRLs in <i>cms</i>.</p>
|
||
|
|
|
||
|
|
<h1 id="NOTES">NOTES</h1>
|
||
|
|
|

|
<p>The CMS_ContentInfo structure <i>cms</i> must be of type signed data or enveloped data or authenticated enveloped data or an error will be returned.</p>
|
||
|
|
|
||
|
|
<p>For signed data, certificates and CRLs are added to the <i>certificates</i> and <i>crls</i> fields of SignedData structure. For enveloped data they are added to <b>OriginatorInfo</b>.</p>

<p>CMS_add0_cert(), CMS_add1_cert() and CMS_add0_crl() and CMS_add1_crl() return 1 for success and 0 for failure.</p>
|
||
|
|
|
||
|
|
<p>CMS_get1_certs() and CMS_get1_crls() return the STACK of certificates or CRLs or NULL if there are none or an error occurs. The only error which will occur in practice is if the <i>cms</i> type is invalid.</p>

|

|
|
|

|
|
<p>CMS_add0_cert() and CMS_add1_cert() have been changed in OpenSSL 3.2 not to throw an error if a certificate to be added is already present.</p>
