  3. CMS_add0_cert, CMS_add1_cert, CMS_get1_certs, CMS_add0_crl, CMS_add1_crl, CMS_get1_crls
  4. - CMS certificate and CRL utility functions
  5. =head1 SYNOPSIS
  6. #include <openssl/cms.h>
  7. int CMS_add0_cert(CMS_ContentInfo *cms, X509 *cert);
  8. int CMS_add1_cert(CMS_ContentInfo *cms, X509 *cert);
  9. STACK_OF(X509) *CMS_get1_certs(CMS_ContentInfo *cms);
  10. int CMS_add0_crl(CMS_ContentInfo *cms, X509_CRL *crl);
  11. int CMS_add1_crl(CMS_ContentInfo *cms, X509_CRL *crl);
  12. STACK_OF(X509_CRL) *CMS_get1_crls(CMS_ContentInfo *cms);
  13. =head1 DESCRIPTION
  14. CMS_add0_cert() and CMS_add1_cert() add certificate B<cert> to B<cms>.
  15. must be of type signed data or enveloped data.
  16. CMS_get1_certs() returns all certificates in B<cms>.
  17. CMS_add0_crl() and CMS_add1_crl() add CRL B<crl> to B<cms>. CMS_get1_crls()
  18. returns any CRLs in B<cms>.
  19. =head1 NOTES
  20. The CMS_ContentInfo structure B<cms> must be of type signed data or enveloped
  21. data or an error will be returned.
  22. For signed data certificates and CRLs are added to the B<certificates> and
  23. B<crls> fields of SignedData structure. For enveloped data they are added to
  24. B<OriginatorInfo>.
  25. As the B<0> implies CMS_add0_cert() adds B<cert> internally to B<cms> and it
  26. must not be freed up after the call as opposed to CMS_add1_cert() where B<cert>
  27. must be freed up.
  28. The same certificate or CRL must not be added to the same cms structure more
  29. than once.
  30. =head1 RETURN VALUES
  31. CMS_add0_cert(), CMS_add1_cert() and CMS_add0_crl() and CMS_add1_crl() return
  32. 1 for success and 0 for failure.
  33. CMS_get1_certs() and CMS_get1_crls() return the STACK of certificates or CRLs
  34. or NULL if there are none or an error occurs. The only error which will occur
  35. in practice is if the B<cms> type is invalid.
