Welcome to J-Blowfish…
J-Blowfish is a Clarion template (Clarion 5.5 upwards), which enables developers to encrypt / decrypt strings, using the highly acclaimed Blowfish algorithm.
Most of the base engine was originally developed by Andy Ireland – we have added a helper class, template wrapper, examples and documentation. Encrypting / decrypting strings can now be done using a single line of code!
This is a free download (with permission from Andy), all that we ask is that you submit any changes that you make to this code back to us.
Enjoy!

Once you have turned on the “Send messages to DebugView” option, recompile and run your APP. You should then see messages appearing in DebugView.
