From: Atousa Pahlevan Duprat <apahle...@ieee.org> The git source uses git_SHA1_Update() and friends to call into the code that computes the hashes. This is can then be mapped directly to an implementation that computes the hash, such as platform_SHA1_Update(); or as we will do in a subsequent patch, it can be mapped to something more complex that will in turn call into the platform's SHA implementation.
