Description

Hi,

Would it be in scope to expose the compression function for blake2?

The usecase I have in mind is to replace this particular function: https://github.com/bluealloy/revm/blob/b8396776a9d53e1553c0396c96a14b461cda17ce/crates/precompile/src/blake2.rs#L55

Research direction

Start with the linked revm entry point, crates/precompile/src/blake2.rs at line 55, and compare that use case with the RustCrypto hashes repository's Blake2 implementation. Clarify the public API and compatibility requirements for exposing the compression function; done means an agreed, documented API with coverage for the intended use case.
