Developer Toolbelt at Mac App Store analyse

Developer Toolbelt provides some handy utilities for developers. The first utility is for Hashing. Currently DT supports SHA1, SHA2 (224,384,256, 512), and MD5 of both strings AND files. Both strings and files can also be hashed with an HMAC key that you provide. The second utility is UUID generation. Not only can you get a truly unique identifier string, but you can also get the Base64 representation of this. All output strings can be copied manually or straight to the clipboard via the Copy button. Super quick and easy!
