perl: please help!

I am trying to encrypt passwords for my website. i was told to download the crypt::Passwdmd5 module from cpan.

i did this. it came in the .tar.gz format.

I used gzip to make the file a .tar file.

I then downloaded and installed tar app to unpack the file.

However whenever i type the command to unpack the file, it gives me an error and exits.

I have been trying for hours!!!

please could someone tell me what to do...

or better would anyone just send me the file(s) i need to put in the perl lib directory ready unpacked. through email, or just attach it to this thread.

Any help would be SOOOOO appreciated. Its doing my head in!!!!!!!
