I use Perl 5.10 ActivePerl 5.14 on win7. I am a humble user, and don't really understand what I am doing.

I have a requirement to connect to a remote host and send locally encrypted messages, using DES ECB mode encryption. This is not my choice, but a part of the requirement. I am trying to find out how to implement DES ECB mode encryption simply in Perl

I do not have access to a C compiler, and cannot be the local administrator on my machine. I don't have download rights either, but can copy / paste source from CPAN into .pm files in my C:. I have copied the source for DES.pm and ECB.pm to C:\Perl 5.10\lib\Crypt\ from CPAN.

In my script I use

use Crypt::ECB qw(encrypt decrypt encrypt_hex decrypt_hex);

and try using it as a proof of concept - the text is from FIPS PUB 81:

print encrypt_hex("0123456789abcdef", "DES", "Now is the time for all ", "1") . "\n";

However, when trying to run this, I see the following error:

Couldn't load Crypt::DES: Attempt to reload Crypt/DES.pm aborted.
Compilation failed in require at (eval 27) line 3.
Are you sure 'DES' is correct? If so, install Crypt::DES in the proper
+ path or choose some other cipher.

I think this is because I don't have a binary for DES (not sure what this means).

I did notice that there is a DES module written in Perl called Crypt::DES_PP. Would using this solve the problem and help me satisfy the requirement? If so, how can I use this module? (Basic, please, I don't understand much!)

Thanks in advance for any assistance!!!
