.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBOSSL_CRMF_MSG_get0_tmpl()\fR retrieves the certificate template of \fIcrm\fR.
.PP
\&\fBOSSL_CRMF_CERTTEMPLATE_get0_publicKey()\fR retrieves the public key of the
given certificate template \fItmpl\fR.
.PP
\&\fBOSSL_CRMF_CERTTEMPLATE_get0_subject()\fR retrieves the subject name of the
given certificate template \fItmpl\fR.
.PP
\&\fBOSSL_CRMF_CERTTEMPLATE_get0_issuer()\fR retrieves the issuer name of the
given certificate template \fItmpl\fR.
.PP
\&\fBOSSL_CRMF_CERTTEMPLATE_get0_serialNumber()\fR retrieves the serialNumber of the
given certificate template \fItmpl\fR.
.PP
\&\fBOSSL_CRMF_CERTTEMPLATE_get0_extensions()\fR retrieves the X.509 extensions
of the given certificate template \fItmpl\fR, or NULL if not present.
.PP
OSSL_CRMF_CERTID_get0_serialNumber retrieves the serialNumber
of the given CertId \fIcid\fR.
.PP
OSSL_CRMF_CERTID_get0_issuer retrieves the issuer name
of the given CertId \fIcid\fR, which must be of ASN.1 type GEN_DIRNAME.
.PP
\&\fBOSSL_CRMF_ENCRYPTEDVALUE_get1_encCert()\fR decrypts the certificate in the given
encryptedValue \fIecert\fR, using the private key \fIpkey\fR, library context
\&\fIlibctx\fR and property query string \fIpropq\fR (see \fBOSSL_LIB_CTX\fR\|(3)).
This is needed for the indirect POPO 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.
.PP
\&\fBOSSL_CRMF_MSG_get_certReqId()\fR retrieves the certReqId of \fIcrm\fR.
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBOSSL_CRMF_MSG_get_certReqId()\fR returns the certificate request ID as a
nonnegative integer or \-1 on error.
.PP
All other functions return a pointer with the intended result or NULL on error.
