user = test {

default service = permit

Any ideeas?

There should be an option in tacas+ to do that.

If not, you could use a program to build one yourself
Quote:
#!/bin/perl

use Crypt:ES;

my $key = pack("H16", "0123456789ABCDEF");
my $cipher = new Crypt:ES $key;
my $ciphertext = $cipher->encrypt("plaintex"); # NB - 8 bytes
print unpack("H16", $ciphertext), "\n";
Have a look here.

Thanks a lot.Acctually I manage to generate the des key with the generate_passwd utility after a long search .... 'generate_passwd is a program to des encrypt a password like Unix. It prompts for the password to encrypt. You can optionally supply a salt to verify a password.'
