.SH NAME
X509_ACERT_add_attr_nconf
\&\- Add attributes to X509_ACERT from configuration section
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& #include <openssl/x509_acert.h>
\&
\& int X509_ACERT_add_attr_nconf(CONF *conf, const char *section,
\&                               X509_ACERT *acert);
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBX509_ACERT_add_attr_nconf()\fR adds one or more \fBX509_ATTRIBUTE\fRs to the
existing \fBX509_ACERT\fR structure \fIacert\fR. The attributes are read
from a \fIsection\fR of the \fIconf\fR object.
.PP
The give \fIsection\fR of the configuration should contain attribute
descriptions of the form:
.PP
.Vb 1
\&  attribute_name = value
.Ve
.PP
The format of \fBvalue\fR will vary depending on the \fBattribute_name\fR.
\&\fBvalue\fR can either be a string value or an \fBASN1_TYPE\fR
object.
.PP
To encode an \fBASN1_TYPE\fR object, use the prefix "ASN1:" followed by
the object description that uses the same syntax as \fBASN1_generate_nconf\fR\|(3).
For example:
.PP
.Vb 1
\& id\-aca\-group = ASN1:SEQUENCE:ietfattr
\&
\& [ietfattr]
\& values = SEQUENCE:groups
\&
\& [groups]
\& 1.string = UTF8:mygroup1
.Ve
.SH "RETURN VALUES"
.IX Header "RETURN VALUES"
\&\fBX509_ACERT_add_attr_nconf()\fR returns 1 for success and 0 for failure.
.SH "SEE ALSO"
.IX Header "SEE ALSO"
\&\fBASN1_generate_nconf\fR\|(3).
.SH HISTORY
.IX Header "HISTORY"
The function \fBX509_ACERT_add_attr_nconf()\fR was added in OpenSSL 3.4.
