GPGTAR(1) GNU Privacy Guard 2.2 GPGTAR(1)

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 format as used by PGP's PGP Zip.

OPTIONS

gpgtar understands these options:

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

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

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.

Extract all files from an encrypted archive.

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 the contents of the specified archive.

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.

Encrypt for user id user. For details see gpg.

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

Write the archive to the specified file file.

Enable extra informational output.

Try to be as quiet as possible.

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

Do not actually output the extracted files.

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 ‘GPGARCH’ is used. For tarball creation, switch to directory dir before performing any operations.

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

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

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

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

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.

Use the specified command gpgcmd instead of gpg.

Pass the specified extra options to gpg.

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

Print version of the program and exit.

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.
