 #include <openssl/crmf.h>

 OSSL_CRMF_CERTTEMPLATE *OSSL_CRMF_MSG_get0_tmpl(const OSSL_CRMF_MSG *crm);
 ASN1_INTEGER
     *OSSL_CRMF_CERTTEMPLATE_get0_serialNumber(OSSL_CRMF_CERTTEMPLATE *tmpl);
 X509_NAME *OSSL_CRMF_CERTTEMPLATE_get0_issuer(OSSL_CRMF_CERTTEMPLATE *tmpl);

 X509_NAME *OSSL_CRMF_CERTID_get0_issuer(const OSSL_CRMF_CERTID *cid);

 X509 *OSSL_CRMF_ENCRYPTEDVALUE_get1_encCert(OSSL_CRMF_ENCRYPTEDVALUE *ecert,
                                             EVP_PKEY *pkey);

 int OSSL_CRMF_MSG_get_certReqId(OSSL_CRMF_MSG *crm);


=head1 DESCRIPTION

OSSL_CRMF_MSG_get0_tmpl() retrieves the certificate template of B<crm>.

OSSL_CRMF_CERTTEMPLATE_get0_serialNumber() retrieves the serialNumber of the
given certificate template B<tmpl>.

OSSL_CRMF_CERTTEMPLATE_get0_issuer() retrieves the issuer name of the
given certificate template B<tmpl>.

OSSL_CRMF_CERTID_get0_serialNumber retrieves the serialNumber
of the given CertId B<cid>.

OSSL_CRMF_CERTID_get0_issuer retrieves the issuer name
of the given CertId B<cid>, which must be of ASN.1 type GEN_DIRNAME.

OSSL_CRMF_ENCRYPTEDVALUE_get1_encCert() decrypts the certificate in the given
encryptedValue B<ecert>, using the private key B<pkey>.
This is needed for the indirect PoP method as in RFC 4210 section 5.2.8.2.
The function returns the decrypted certificate as a copy, leaving its ownership
with the caller, who is responsible for freeing it.

OSSL_CRMF_MSG_get_certReqId() retrieves the certReqId of B<crm>.


=head1 RETURN VALUES

OSSL_CRMF_MSG_get_certReqId() returns the certificate request ID as a
non-negative integer or -1 on error.

All other functions return a pointer with the intended result or NULL on error.

=head1 SEE ALSO

B<RFC 4211>

The OpenSSL CRMF support was added in OpenSSL 3.0.
