.SH "NAME"
srsd \- daemon interface to Mail::SRS
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
srsd \-\-secretfile=/etc/srs_secret
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The srsd daemon listens on a socket for \s-1SRS\s0 address transformation
requests. It transforms the addresses and returns the new addresses
on the socket.
.PP
It may be used from exim using ${readsocket ...}, from sendmail via
a \s-1TCP\s0 socket in a rule, and probably from other MTAs as well. See
http://www.anarres.org/projects/srs/ for examples.
.PP
Arguments take the form \-\-name or \-\-name=value.
.SH "ARGUMENTS"
.IX Header "ARGUMENTS"
.SS "\-\-separator"
.IX Subsection "--separator"
String, specified at most once. Defaults to \f(CW$SRSSEP\fR (\f(CW\*(C`=\*(C'\fR).
.PP
Specify the initial separator for the \s-1SRS\s0 address. See Mail::SRS for
details.
.SS "\-\-secret"
.IX Subsection "--secret"
String, may be specified multiple times, at least one of \-\-secret or
\&\-\-secretfile must be specified.
.PP
Specify an \s-1SRS\s0 secret. The first specified secret is used for
encoding. All secrets are used for decoding.
.SS "\-\-secretfile"
.IX Subsection "--secretfile"
String, specified at most once, at least one of \-\-secret or
\&\-\-secretfile must be specified.
.PP
A file to read for secrets. Secrets are specified once per line. The
first specified secret is used for encoding. Secrets are written
one per line. Blank lines and lines starting with a # are ignored.
If \-\-secret is not given, then the secret file must be nonempty.
.PP
\&\-\-secret will specify a primary secret and override \-\-secretfile
if both are specified. However, secrets read from \-\-secretfile will
still be used for decoding if both are specified.
.SS "\-\-hashlength"
.IX Subsection "--hashlength"
Integer, may be specified at most once, defaults to 4.
.PP
Specify the number of base64 characters to use for the cryptographic
authentication code.
.SS "\-\-help"
.IX Subsection "--help"
Print some basic help.
.SH "PROTOCOL"
.IX Header "PROTOCOL"
