crypto: use EVP_MD_fetch and cache EVP_MD for hashes by joyeecheung · Pull Request #51034 · nodejs/node · GitHub

On OpenSSL 3, migrate from EVP_get_digestbyname() to EVP_MD_fetch() to get the implementation and use a per-Environment cache for it. The EVP_MDs are freed during Environment cleanup.

Drive-by: declare the smart pointer for EVP_MD_CTX as EVPMDCtxPointer instead of EVPMDPointer to avoid confusion with EVP_MD pointers.

Updated to cache all the explicitly fetched implementations from getHashes() and map the supported algorithms to indices into the cache (now a vector). Locally on macOS + M2 the performance improvement is better:

Will caching the fetches run into issues given that OpenSSL 3 providers are dynamic (although we don't have an API in Node.js for this but one could feasibly write an addon to unload/load providers)?

Will caching the fetches run into issues given that OpenSSL 3 providers are dynamic (although we don't have an API in Node.js for this but one could feasibly write an addon to unload/load providers)?

I think for our built-in APIs we always do the implicit fetching with no additional library context or provider property configured (because we use EVP_get_digestbyname()) so it's never reliable for any addon to count on the providers they load to affect the built-in APIs. Whether we want to support an explicit provider from the native API would be a different matter, but I think that would be orthogonal to this issue (we can just hook the cache into the explicit native API, or give up on caching if addons configure an explicit provider).
