MD5Generator/SHA256Processor

[yairadix]

I want to do a simple regression testing for audio plugins - test that the plugin’s output doesn’t change when I do refactors which I don’t expect to change the plugin’s behaviour.

I was thinking of doing some processBlocks in some loop and hashing its content, but JUCE’s hash functions don’t support a streaming interface

JUCE implements MD5Generator/SHA256Processor internally but those aren’t exposed, would it be reasonable to request exposing a streaming hashing API? To reimplement or use another library for a hash implementation while it is already implemented in JUCE seems like a waste.

I guess this can work as a quasi bump for this :

Any reason the hash classes don't accept partial data?

When hashing stuff, I usually need to do something like this with the JUCE hash classes : MD5 getHash() const { MemoryBlock mb; for (int i = 0; i < m_nodes.size(); ++i) { mb.append((void*)&m_nodes[i].Time, sizeof(double)); mb.append((void*)&m_nodes[i].Value, sizeof(double)); mb.append((void*)&m_nodes[i].ShapeParam1, sizeof(double)); mb.append((void*)&m_nodes[i].ShapeParam2, sizeof(double)); } return MD5(mb); } It would be great to avoid having to construct and fill the temporary…
