TeaTime/2 v0.05 - A XTea file encryption program

Please check your country's cryptography import/export control laws before downloading. Both me and the webspace provider have no resposibility for violation of crypto laws. The person performing the download is responsible in any case!

Introduction

TeaTime/2 is a file encryption program for OS/2 based on the simple, fast and secure XTea cipher (which is an improved version of the Tiny Encryption Algorithm). XTea is a block cipher with an 128-bit key, primarily using 32-bit operations making it fast on 386 and later processors. TeaTime/2 is compiled using the Mill Hill & Canterbury Modula-2 compiler for OS/2.

Usage

Syntax: teatime <-d|-e> [key]

The key parameter is optional, if it is omitted TeaTime/2 will ask for the password interactively.

Feedback is appreciated, even a message telling me it works fine on your OS/2 version.
