NAME¶debsigs - process signatures in .deb packages
SYNOPSIS¶debsigs --list|-l [-v] file [file...]
debsigs --sign=type [--default-key=keyID] [-v] file [file...]
debsigs --verify|--check|-c file [file...]
debsigs --delete=type file [file...]
DESCRIPTION¶debsigs is used to manipulate the cryptographic signatures stored inside a .deb file. It is not used to verify those signatures; for that purpose, see debsig-verify(1).
- --list or -l or -t
- Lists the signatures found in the specified file.
- Creates a new signature of the type specified in the given file. The signature will be created using the default key for your GPG keyring. See "SIGNATURE TYPES" below for possible values of the "type" field.
- Uses a key other than the default for signing the package.
- --secret-keyring=file or -K file
- Uses a keyring other than the default for signing the package. This option is passed along to GPG verbatim; see the discussion in the gpg(1) manpage for information on how to specify the keyring file.
- Displays verbose output.
- --verify or --check or -c
- Invokes debsig-verify to check the validity of the signature on this package.
- Deletes the signature of the specified type from the package.
SIGNATURE TYPES¶A Debian package may carry different types of signatures. The most commonly-used ones are:
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.
The signature of the maintainer of the Debian package. This signature should be added by the maintainer before uploading the package.
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.
See the /usr/share/doc/debsigs/signing-policy.txt file for more information and rationale for the different signature types.
FUTURE DIRECTIONS¶It would be nice to have a command-line option to change the command used for signing, instead of hard-coding "gpg".
