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.
- --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.
- 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.
- --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. 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.
- 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.
- --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.
- 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.
