CMS_add0_cert(3)                    OpenSSL                   CMS_add0_cert(3)



NAME
       CMS_add0_cert, CMS_add1_cert, CMS_get1_certs, CMS_add0_crl,
       CMS_add1_crl, CMS_get1_crls - CMS certificate and CRL utility functions

LIBRARY
       libcrypto, -lcrypto

SYNOPSIS
        #include <openssl/cms.h>

        int CMS_add0_cert(CMS_ContentInfo *cms, X509 *cert);
        int CMS_add1_cert(CMS_ContentInfo *cms, X509 *cert);
        STACK_OF(X509) *CMS_get1_certs(CMS_ContentInfo *cms);

        int CMS_add0_crl(CMS_ContentInfo *cms, X509_CRL *crl);
        int CMS_add1_crl(CMS_ContentInfo *cms, X509_CRL *crl);
        STACK_OF(X509_CRL) *CMS_get1_crls(CMS_ContentInfo *cms);

DESCRIPTION
       CMS_add0_cert() and CMS_add1_cert() add certificate cert to cms.  This
       is used by CMS_sign_ex(3) and CMS_sign(3) and may be used before
       calling CMS_verify(3) to help chain building in certificate validation.
       cms 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.

       CMS_get1_certs() returns all certificates in cms.

       CMS_add0_crl() and CMS_add1_crl() add CRL crl to cms.  cms must be of
       type signed data or (authenticated) enveloped data.  For signed data,
       such a CRL may be used in certificate validation with CMS_verify(3).
       It may be given both for inclusion when signing a CMS message and when
       verifying a signed CMS message.

       CMS_get1_crls() returns all CRLs in cms.

NOTES
       The CMS_ContentInfo structure cms must be of type signed data or
       enveloped data or an error will be returned.

       For signed data certificates and CRLs are added to the certificates and
       crls fields of SignedData structure. For enveloped data they are added
       to OriginatorInfo.

       As the 0 implies CMS_add0_cert() adds cert internally to cms and it
       must not be freed up after the call as opposed to CMS_add1_cert() where
       cert must be freed up.

       The same certificate must not be added to the same cms structure more
       than once.

RETURN VALUES
       CMS_add0_cert(), CMS_add1_cert() and CMS_add0_crl() and CMS_add1_crl()
       return 1 for success and 0 for failure.

       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 cms type is invalid.
