in reply to Encryption in Perl

You can look on CPAN for crypt-related modules. Try this. I'd suggest a specific module but it really depends on what you're trying to do.

    Basically I am trying to do the following. Imagine some messages are being exchanged between two users.At each endpoint information is stored based on the messages. Now in order to access this information I want to create a key or a hash based on some content that is common to all the messages that are exchanged eg. address, name, phone number etc. What do you think I could use for this case? All help appreciated!! Cheers, Valerie

      In pure Perl, you don't need encryption at all if you don't really need to keep the data hidden. A simple hash data type will suffice:

      my %data;
while(my $msg = get_msg()) {
    $data{$msg} = 1;
}

      If you need to save this to a file or a database or whatever, you can use the Digest::MD5 or Digest::SHA1. Note: MD5 is possibly on the verge of collapse as far as security is concerned, so stay away from it if you need it for security reasons. MD5 is fine if you just need the hash properties, and it will be faster than SHA1.
