8.12 Encrypt or sign files into an archive

gpg-zip encrypts or signs files into an archive. It is an gpg-ized tar using the same format as used by PGP's PGP Zip.

gpg-zip is invoked this way:

     gpg-zip [options] filename1 [filename2, ...] directory [directory2, ...]

gpg-zip understands these options:

--encrypt
-e
Encrypt data. This option may be combined with --symmetric (for output that may be decrypted via a secret key or a passphrase).
--decrypt
-d
Decrypt data.
--symmetric
-c
Encrypt with a symmetric cipher using a passphrase. The default symmetric cipher used is CAST5, but may be chosen with the --cipher-algo option to gpg.
--sign
-s
Make a signature. See gpg.
--recipient user
-r user
Encrypt for user id user. See gpg.
--local-user user
-u user
Use user as the key to sign with. See gpg.
--list-archive
List the contents of the specified archive.
--output file
-o file
Write output to specified file file.
--gpg gpgcmd
Use the specified command gpgcmd instead of gpg.
--gpg-args args
Pass the specified options to gpg.
--tar tarcmd
Use the specified command tarcmd instead of tar.
--tar-args args
Pass the specified options to tar.
--version
Print version of the program and exit.
--help
Display a brief help page and exit.

The program returns 0 if everything was fine, 1 otherwise.

Some examples:

Encrypt the contents of directory mydocs for user Bob to file test1:

     gpg-zip --encrypt --output test1 --gpg-args  -r Bob mydocs

List the contents of archive test1:

     gpg-zip --list-archive test1
