cisco-decrypt <obfuscated pre-shared key>
This command accompanies vpnc. It decrypts the obfuscated pre-shared key from *.pcf-configuration files, which must be specified on the command line.
The result will be printed to STDOUT.
cisco-decrypt was originally written by Maurice Massar. This man-page was written by Jörg Mayer, based on the pcf2vpnc manpage written by Wolfram Sang (ninja(at)the-dreams.de).
