date cipher

Yarek — Tue, 20 Nov 2007 07:17:00 GMT

Hello Masters!

I'm looking for a tool which can compress some data with password.
The tool should be integrated part of OS.

Any advice?

Thanks in advance

Archive and compress your files using the utility apps of your choice (e.g. 'tar', 'gzip', 'compress', 'bzip2'). Then run the resulting file through 'crypt'.

$ crypt password < infile.tar.gz > outfile.tar.gz

Decrypt by reversing the order of infile and outfile in the above command.

Not particulary secure, but:

crypt < myfile | gzip > myfile.crypt.gz

will do it (you'll be prompted for a key)

uncrypt using

gzcat myfile.crypt.gz | crypt > myfile

Heed the warning about the level of security provided by crypt in the man page:

crypt implements a one-rotor machine designed along the lines of the
German Enigma, but with a 256-element rotor. Methods of attack on
such machines are widely known; thus crypt provides minimal security.

Hi Yarek,

you can compress files with "tar" or "gzip" and then seal it with "crypt" command

This should do it
