roundtrip

Overview ¶

Command roundtrip-example embeds a message and extracts it back, exercising the embed and extract packages together.

The extract package follows dependency injection: the caller supplies a Hasher (SHA-1) and a Permutator (Fisher-Yates) plus the PRNG factory, so the extraction PRNG path mirrors embedding exactly. The two small adapters below bridge the upstream sha1 and fisheryates primitives to the extract interfaces.
