Privacy is a basic human right and I will always fight to protect this right.

"No one shall be subjected to arbitrary interference with his privacy, family,
home or correspondence..."
- Article 12, Universal Declaration of Human Rights

FileCrypt is a simple utility for securely encrypting individual files using Gnu Privacy Guard (GPG) for maximum, military grade encryption.

It's designed to be as simple to use as possible, with a straight-forward drag and drop interface.

Full source code is provided, so that a) people can confirm there are no hidden backdoors and b) RISC OS programmers can see how to build a simple wimp interface to their applications.

Those interested in privacy and fighting to keep it, may be interested in my other crypto software or in visiting Dr Nat Queen's excellent Acorn crypto pages.
