I have two Perl installation on my PC: ActiveState (AS) and the one from Cygwin. I use AS as my Perl dev/test environment while I use Cygwin mainly for its Unix tools.
I have created a Perl script for data encryption/decryption using Crypt::Twofish_PP. It works great but is much too slow. Thus, I decided to go to Crypt::Rijndael. Its improved performances come mainly from its compiled-C component.
To create the Rijndael module, I had to use Cygwin's gcc compiler. Everything worked like a charm. The only problem is that the module is installed in Cygwin's Perl setup. How do I transfer it over to my AS setup?
Cygwin looks impressive for dev/test purposes. I will probably go to it in the future but I still need AS at the moment.
