.SH NAME
getpublickey, getsecretkey, publickey \- retrieve public or secret key
.SH SYNOPSIS
.LP

#include <rpc/rpc.h>
#include <rpc/key_prot.h>

\fBint\fR \fBgetpublickey\fR(\fBconst char\fR \fInetname[MAXNETNAMELEN]\fR,

\fBint\fR \fBgetsecretkey\fR(\fBconst char\fR \fInetname[MAXNETNAMELEN]\fR,
     \fBchar\fR \fIsecretkey[HEXKEYBYTES+1]\fR,\fBconst char *\fR\fIpasswd\fR);
.fi

.SH DESCRIPTION
.LP
The \fBgetpublickey()\fR and \fBgetsecretkey()\fR functions get public and
secret keys for \fInetname\fR. The key may come from one of the following
sources:
.RS +4
.TP
.ie t \(bu
.el o
\fB/etc/publickey\fR file. See \fBpublickey\fR(4).
.RE
.RS +4
.TP
.ie t \(bu
.el o
\fBNIS\fR map ``publickey.byname''.
The sources and their lookup order are specified in the
\fB/etc/nsswitch.conf\fR file. See \fBnsswitch.conf\fR(4).
.RE
.sp
.LP
\fBgetsecretkey()\fR has an extra argument, \fBpasswd\fR, which is used to
decrypt the encrypted secret key stored in the database.
.SH RETURN VALUES
.LP
Both routines return \fB1\fR if they are successful in finding the key.
Otherwise, the routines return \fB0\fR. The keys are returned as
null-terminated, hexadecimal strings. If the password supplied to
\fBgetsecretkey()\fR fails to decrypt the secret key, the routine will return 1
but the \fIsecretkey\fR [0] will be set to \fINULL\fR.
