.SH "NAME"
srs \- command line interface to Mail::SRS
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
srs \-\-alias=alias@forwarder.com \-\-secretfile=/etc/srs_secret \e
		sender@source.com
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The srs commandline interface will create an instance of Mail::SRS
with parameters derived from the commandline arguments and perform
forward or reverse transformations for all addresses given.
.PP
It is usually invoked from a sendmail envelope address
transformation rule, a qmail alias, or similar. 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 "\-\-address"
.IX Subsection "--address"
String, may be specified multiple times, must be specified at least
once.
.PP
Specify a sender address to transform.
.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 "\-\-forward"
.IX Subsection "--forward"
No argument.
.PP
Specifies a forwards transformation. This is the default. \-\-reverse
must not also be given.
.SS "\-\-reverse"
.IX Subsection "--reverse"
No argument.
.PP
Specifies a reverse transformation. \-\-forward must not also be given.
.SS "\-\-alias"
.IX Subsection "--alias"
String, must be specified exactly once if doing forwards transformation.
.PP
Provides the alias address to which the mail was sent. The domain-part
of this address is used in the generated \s-1SRS\s0 address. The local-part
and @ are optional and may be omitted.
.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.
