Description

I am trying to compute the name hash for CRLs (X509Name.hash() in pyopenssl), and it seems there is no equivalent operation in the cryptography package. The closest I can find is Name.public_bytes(), but that only gives me X509Name.der(). I tried reproducing the steps in hash()'s documentation, but I'm getting a different hash than openssl. Not to mention the process is internal and may be subject to change.

What is the suggested replacement for pyopenssl's X509Name.hash()?

Research direction

Start by reviewing the issue's references to pyopenssl's X509Name.hash(), cryptography's Name.public_bytes(), and the documented hash computation steps. Compare the expected OpenSSL result with the available public APIs, then determine whether a supported replacement can be identified or needs to be proposed and documented.
