macula_content_hasher (macula v0.20.5)
View SourceContent hashing module for Macula content-addressed storage.
Provides cryptographic hashing using BLAKE3 (primary) and SHA256 (fallback). BLAKE3 uses a pure Erlang implementation that can be optimized with NIFs from macula-nifs/ for production use.
Example Usage
%% Hash binary data
Hash = macula_content_hasher:hash(blake3, Data).
%% Verify hash
true = macula_content_hasher:verify(blake3, Data, Hash).
%% Stream hash multiple chunks
Hash = macula_content_hasher:hash_streaming(sha256, [Chunk1, Chunk2]).Summary
Functions

Hash a list of binary chunks using streaming (memory efficient).
Decode hex string to binary.
Encode binary to lowercase hex string.
Check if an algorithm is supported.
Return list of supported hash algorithms.
Verify that data matches the expected hash.
