Detailed Description

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

Once an ECHO computation has been performed, the context can be reused for another computation. This specific structure is used for ECHO-224 and ECHO-256.

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