Installing Crypt::Blowfish

crabbdean has asked for the wisdom of the Perl Monks concerning the following question:

I've created a password encrypting application. Currently it uses Crypt::CBC with Crypt::DES_EDE3 as the cipher. Its all working fine. BUT ... initially I wanted to use Crypt::Blowfish because from what I understand this is a better encryption algorithm. Problem is ... I'm on a win32 system and you can't install Blowfish with ppm3 (its not available on ppm3). I've attempted to download and install Blowish module from CPAN using nmake. I get the below error

I've read the README notes. Not knowing a lot about this installing method I'm a little stuck. Call me retarted but I'm calling on people who know a little more about this than me. Thanks. :-)

Yes, you require a C compiler to build the XS parts of the module. You can download the VC++ Toolkit here, you may also require some additional stuff from the Win32 SDK. /J\	[reply]

Or, the easy way is to get a "ppm"ed package from this repository: http://theoryx5.uwinnipeg.ca/ppms/ If you are unable to get to the repository, download & edit the ppd, to find where the corresponding .tar.gz package is, download it and create your own local repository. -- Olivier	[reply]

Thanks (++) to both of you. Both answers were helpful. I'll look more into J's answer later as its an area I want to learn more about, but at this juncture Olivier's answer gave immediate results. I ppm'd into the your suggested repository and it immediately installed (hassle free!), changed my program to utilise Blowfish and ran the encryption. Perfect! All done in less than a minute. A big cheers!

Crypt::Rijndael looks like it is available in the ActiveState repository. Rijndael is the AES standard and a better algorithm than DES or Blowfish. Since it is available, and standard, you might as well use it.	[reply]
