Detailed Description

This structure is a context for Groestl-384 and Groestl-512 computations: it contains the intermediate values and some data from the last entered block.

Once a Groestl computation has been performed, the context can be reused for another computation.

The contents of this structure are private. A running Groestl computation can be cloned by copying the context (e.g. with a simple memcpy()).
