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.
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.
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.
