HaSHAr

The overall design goal of HaSHAr is to provide a simple-to-use file verification tool for use on Mac OSX. File verification should:

• Utilize the latest performance-enhanced libraries within OSX, e.g., Grand Central Dispatch [(GCD)] 1 and async file I/O;
• Be based on a cryptographically-strong message digest algorithm, e.g., [SHA1] 2
• Provide a simple, human-readable side-car file containing the hash of the file. For example, file "MyFile.txt" would have a corresponding "MyFile.txt.sha1" side-car containing a hex-encoded string.

Other goals include:

• Share with the open source developer community;
• Aid in a learning opportunity;

Current Status

There are two (2) build targets for XCode 4:

• CLI: for command line execution

The CLI target is fully functional and can be use to generate/verify files based on file extensions.

• haSHAr_: GUI control

The haSHAr GUI target is a Work in Progress. This is

See the target's respective README.md file for more information.
