Detailed Description

Helper class to perform a sha1 calculation.

Basic usage:

• construct a SHA1 object
• repeatedly call update()
• call digest() to get the result Alternatively, use calc() if all data can be passed at once (IOW when there would be exactly one call to update() in the recipe above).
