| 20 =head1 DESCRIPTION |
| 21 |
| 22 CMS_add0_cert() and CMS_add1_cert() add certificate B<cert> to B<cms>. |
| 23 must be of type signed data or enveloped data. |
| 24 |
| 25 CMS_get1_certs() returns all certificates in B<cms>. |
| 26 |
| 27 CMS_add0_crl() and CMS_add1_crl() add CRL B<crl> to B<cms>. CMS_get1_crls() |
| 28 returns any CRLs in B<cms>. |
| 29 |
| 30 =head1 NOTES |
| 31 |
| 32 The CMS_ContentInfo structure B<cms> must be of type signed data or enveloped |
| 33 data or an error will be returned. |
| 34 |
| 35 For signed data certificates and CRLs are added to the B<certificates> and |
| 36 B<crls> fields of SignedData structure. For enveloped data they are added to |
| 37 B<OriginatorInfo>. |
| 38 |
| 39 As the B<0> implies CMS_add0_cert() adds B<cert> internally to B<cms> and it |
| 40 must not be freed up after the call as opposed to CMS_add1_cert() where B<cert> |
| 41 must be freed up. |
| 42 |
| 43 The same certificate or CRL must not be added to the same cms structure more |
| 44 than once. |
| 45 |
| 46 =head1 RETURN VALUES |
| 47 |
| 48 CMS_add0_cert(), CMS_add1_cert() and CMS_add0_crl() and CMS_add1_crl() return |
| 49 1 for success and 0 for failure. |
| 50 |
| 51 CMS_get1_certs() and CMS_get1_crls() return the STACK of certificates or CRLs |
| 52 or NULL if there are none or an error occurs. The only error which will occur |
| 53 in practice is if the B<cms> type is invalid. |
