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. 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 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() 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.
