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. If no file name is given (or it is "-") the archive is taken from stdin.
--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. If no file name is given (or it is "-") the archive is taken from stdin. | ||
--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. If no file name is given (or it is "-") the archive is taken from stdin. |
--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. 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 encrypt or sign using the CMS protocol; but that is not yet implemented. |
--batch
Use batch mode. Never ask but use the default action. This option is passed directly to gpg.
--yes |
Assume "yes" on most questions. Often used together with --batch to overwrite existing files. This option is passed directly to gpg. | ||
--no |
Assume "no" on most questions. This option is passed directly to gpg. |
--require-compliance
This option is passed directly to gpg.
--status-fd n
Write special status strings to the file descriptor n. See the file DETAILS in the documentation for a listing of them.
--with-log
When extracting an encrypted tarball also write a log file with the gpg output to a file named after the extraction directory with the suffix ".log".
--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.
--no-compress
This option tells gpg to disable compression (i.e. using option -z0). It is useful for archiving only large files which are are already compressed (e.g. a set of videos).
--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.
--tar command
This is a dummy option for backward compatibility.
--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.
