.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fIdebsigs\fR is used to manipulate the cryptographic signatures stored inside
a .deb file.  It is not used to verify those signatures; for that purpose,
see \fBdebsig\-verify\fR\|(1).
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-\-list\fR or \fB\-l\fR or \fB\-t\fR" 5
.IX Item "--list or -l or -t"
Lists the signatures found in the specified file.
.IP "\fB\-\-sign=type\fR" 5
.IX Item "--sign=type"
Creates a new signature of the type specified in the given file.
The signature will be created using the default key for your \s-1GPG\s0 keyring.
See \*(L"\s-1SIGNATURE TYPES\*(R"\s0 below for possible values of the \f(CW\*(C`type\*(C'\fR field.
.IP "\fB\-\-default\-key=keyID\fR" 5
.IX Item "--default-key=keyID"
Uses a key other than the default for signing the package.
.IP "\fB\-\-secret\-keyring=file\fR or \fB\-K file\fR" 5
.IX Item "--secret-keyring=file or -K file"
Uses a keyring other than the default for signing the package.  This
option is passed along to \s-1GPG\s0 verbatim; see the discussion in the \fBgpg\fR\|(1)
manpage for information on how to specify the keyring file.
.IP "\fB\-v\fR" 5
.IX Item "-v"
Displays verbose output.
.IP "\fB\-\-verify\fR or \fB\-\-check\fR or \fB\-c\fR" 5
.IX Item "--verify or --check or -c"
Invokes debsig-verify to check the validity of the signature on this
package.
.IP "\fB\-\-delete=type\fR" 5
.IX Item "--delete=type"
Deletes the signature of the specified type from the package.
.SH "SIGNATURE TYPES"
.IX Header "SIGNATURE TYPES"
A Debian package may carry different types of signatures.  The most
commonly-used ones are:
.IP "\(bu" 4
\&\f(CW\*(C`origin\*(C'\fR
.Sp
The official signature of the organization which distributes
the package, usually the Debian Project or a GNU/Linux distribution
derived from it.  This signature may be added automatically.
.IP "\(bu" 4
\&\f(CW\*(C`maint\*(C'\fR
.Sp
The signature of the maintainer of the Debian package.  This signature
should be added by the maintainer before uploading the package.
.IP "\(bu" 4
\&\f(CW\*(C`archive\*(C'\fR
.Sp
An automatically-added signature renewed periodically to ensure
that a package downloaded from an online archive is indeed
the latest version distributed by the organization.
.PP
See the \fI/usr/share/doc/debsigs/signing\-policy.txt\fR file for
more information and rationale for the different signature types.
.SH "FUTURE DIRECTIONS"
.IX Header "FUTURE DIRECTIONS"
It would be nice to have a command-line option to change the command used
for signing, instead of hard-coding \*(L"gpg\*(R".
