gpgtar - Encrypt or sign files into an archive
gpgtar [options] filename1 [ filename2, ... ] directory1 [ directory2, ... ]
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.
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 ‘GPGARCH’ is used. --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. --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 encrypt 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 supported tar options are "--directory", "--files-from", and "--null" This is an obsolete 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.
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
The program returns 0 if everything was fine, 1 otherwise.
