.. Set up some character translations and predefined strings. \*(-- will
give an unbreakable dash, \*(PI will give pi, \*(L" will give a left
double quote, and \*(R" will give a right double quote. \*(C+ will
give a nicer C++. Capital omega is used to do unbreakable dashes and
therefore won't be available. \*(C` and \*(C' expand to `' in nroff,
nothing in troff, for use with C<>.

Escape single quotes in literal strings from groff's Unicode transform.

If the F register is >0, we'll generate index entries on stderr for
titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
entries marked with X<> in POD. Of course, you'll have to process the
output yourself in some meaningful fashion.

Avoid warning from groff about undefined register 'F'.

Title "CMS_ADD0_CERT 3ossl" For nroff, turn off justification. Always turn off hyphenation; it makes
way too many mistakes in technical documents.
CMS_add0_cert, CMS_add1_cert, CMS_get1_certs, CMS_add0_crl, CMS_add1_crl, CMS_get1_crls \- CMS certificate and CRL utility functions Header "SYNOPSIS" .Vb 1 #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); .Ve Header "DESCRIPTION" \fBCMS_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. \fIcms 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 \s-1CA\s0 certificate that may be needed for chain building in certificate validation.

\fBCMS_get1_certs() returns all certificates in cms.

\fBCMS_add0_crl() and CMS_add1_crl() add \s-1CRL\s0 crl to cms. \fIcms must be of type signed data or (authenticated) enveloped data. For signed data, such a \s-1CRL\s0 may be used in certificate validation with CMS_verify\|(3). It may be given both for inclusion when signing a \s-1CMS\s0 message and when verifying a signed \s-1CMS\s0 message.

\fBCMS_get1_crls() returns all CRLs in cms.

Header "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 \fIcrls fields of SignedData structure. For enveloped data they are added to \fBOriginatorInfo.

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.

Header "RETURN VALUES" \fBCMS_add0_cert(), CMS_add1_cert() and CMS_add0_crl() and CMS_add1_crl() return 1 for success and 0 for failure.

\fBCMS_get1_certs() and CMS_get1_crls() return the \s-1STACK\s0 of certificates or CRLs or \s-1NULL\s0 if there are none or an error occurs. The only error which will occur in practice is if the cms type is invalid.
