NAME
gpgtar - Encrypt or sign files into an archive

SYNOPSIS
gpgtar [options] filename1 [ filename2, ... ] directory1 [ directory2, ... ]

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

OPTIONS
gpgtar understands these options:

--create
Put given files and directories into a vanilla ``ustar'' archive.

--extract
Extract all files from a vanilla ``ustar'' archive.

--encrypt
-e Encrypt given files and directories into an archive. This option may be combined
with option --symmetric for an archive that may be decrypted via a secret key or a
passphrase.

--decrypt
-d Extract all files from an encrypted archive.

--sign
-s Make a signed archive from the given files and directories. This can be combined
with option --encrypt to create a signed and then encrypted archive.

--list-archive
-t List the contents of the specified archive.

--symmetric
-c Encrypt with a symmetric cipher using a passphrase. The default symmetric cipher
used is AES-128, but may be chosen with the --cipher-algo option to gpg.

--recipient user
-r user
Encrypt for user id user. For details see gpg.

--local-user user
-u user
Use user as the key to sign with. For details see gpg.

--output file
-o file
Write the archive to the specified file file.

--verbose
-v Enable extra informational output.

--quiet
-q Try to be as quiet as possible.

--skip-crypto
Skip all crypto operations and create or extract vanilla ``ustar'' archives.

--dry-run
Do not actually output the extracted files.

--directory dir
-C dir Extract the files into the directory dir. The default is to take the directory
name from the input filename. If no input filename is known a directory named 'GP-
GARCH' is used. For tarball creation, switch to directory dir before performing
any operations.

--files-from file
-T file
Take the file names to work from the file file; one file per line.

--null Modify option --files-from to use a binary nul instead of a linefeed to separate
file names.

--utf8-strings
Assume that the file names read by --files-from are UTF-8 encoded. This option has
an effect only on Windows where the active code page is otherwise assumed.

--openpgp
This option has no effect because OpenPGP encryption and signing is the default.

--cms This option is reserved and shall not be used. It will eventually be used to en-
crypt or sign using the CMS protocol; but that is not yet implemented.

--set-filename file
Use the last component of file as the output directory. The default is to take the
directory name from the input filename. If no input filename is known a directory
named 'GPGARCH' is used. This option is deprecated in favor of option --directory.

--gpg gpgcmd
Use the specified command gpgcmd instead of gpg.

--gpg-args args
Pass the specified extra options to gpg.

--tar-args args
Assume args are standard options of the command tar and parse them. The only sup-
ported tar options are "--directory", "--files-from", and "--null" This is an obso-
lete options because those supported tar options can also be given directly.

--version
Print version of the program and exit.

--help Display a brief help page and exit.

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

gpgtar --encrypt --output test1 -r Bob mydocs

List the contents of archive 'test1':

gpgtar --list-archive test1

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