How to generate the hash of public key in Bitcoin
I'm starting to wonder how difficult it is to find people who are helping others in this site


I don't have your same idea, but sorry for the delay in the answer but in Italy exist at the moment the alert "coronavirus".

My test to resolve your problem

I don't know the language of the code that you have public in the question but I have a project to decompiler script bitcoin but is in the start phases.

I'm answering with C++ code.

Exist two types of Public key, that is compressed and uncompressed, the difference is:


Compressed public key started with a flag "02" (I think this is your cases)
Uncompressed start with the flag "03"
If the you key start with "04" doesn't is the public key but is a P2PK script.


But a good reference that explains the compressed public key is this What is a compressed Bitcoin key? 

So, I think your error is the public key input,your public key is 02b4632d08485ff1df2db55b9dafd23347d1c47a457072a1e87be26896549a8737 and not 2b4632d08485ff1df2db55b9dafd23347d1c47a457072a1e87be26896549a8737, you have lose the the part of flag of the compressed public key.

So, my C++ code to test my idea is this:

    cout &lt;&lt; "Test for Bitcoin.stack question" &lt;&lt; endl;
    cout &lt;&lt; "Public Key: " &lt;&lt; "02b4632d08485ff1df2db55b9dafd23347d1c47a457072a1e87be26896549a8737\n";
    string keyTmp = "02b4632d08485ff1df2db55b9dafd23347d1c47a457072a1e87be26896549a8737";
    string flag = keyTmp.substr(0, 2);
    if(flag == "02"){
          cout &lt;&lt; "Compressed with y event";
    }else if(flag == "03"){
      cout &lt;&lt; "Compressed with y odd";
    }else{
      assert(flag == "04");
    }
    Bytes bytesTmp = hexBytes(keyTmp.c_str());

    //SHA256
    Sha256Hash shaHash = Sha256::getHash(bytesTmp.data(), bytesTmp.size());
    uint8_t result[Ripemd160::HASH_LEN];
    Ripemd160::getHash(shaHash.value, sizeof(shaHash), result);

    cout &lt;&lt; "Hash Public key: " &lt;&lt; ToString(result);


The hash public key ofter run this code is: 93ce48570b55c42c2af816aeaba06cfee1224fae 

References

The reference of the project are off-topics here but I think without it this post can be fake, so I'm adding the reference of the library used to implement my code in this answer.
