This is an update to my simple, easy-to-use checksum calculator. It supports md4, md5, and sha1 hash functions. I wrote the project as a way to experiment with and learn Qt.

Changes since the previous version (Hash Puppy 0.1) include the ability to abort a checksum calculation and improved GUI responsiveness. There were also other minor tweaks to make Hash Puppy easier to use.
The software is available under the GPL license.
Source code: hashpuppy-0.2.tar.gz
Binary for Windows: hashpuppy-0.2.zip (Compiled against Qt 4.6.2).
