This feature decrypts passwords stored in profile files (*.pcf) by Cisco VPN Client software. These files contain all the parameters needed to connect to a remote network via VPN tunnels.
Keys generated by Cisco software’s encryption algorithm are created using SHA1 and 3DES in EDE mode. They are user and machine independent.
Simply cut and paste the encrypted password (enc_GroupPwd or enc_UserPassword) into the dialog; the decoder will do the rest.
