Parameters

data: The data to hash; no length restriction.

Return Value

A 32-byte SHA256Digest.

Discussion

The shim wraps the internal libsecp256k1 SHA-256 implementation so the Swift layer and the C layer share a single implementation for all hashing operations that feed into signing / verification.
