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

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. cms must be of type signed data or enveloped data.

CMS_get1_certs() returns all certificates in cms.

CMS_add0_crl() and CMS_add1_crl() add CRL crl to cms. CMS_get1_crls() returns any 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 the 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 or CRL must not be added to the same cms structure more than once.

RETURN VALUES
CMS_add0_cert(), CMS_add1_cert(), 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.
