Getting wrong result from SHA256 than what is expected

Question

I am trying to derive a bitcoin address from a known public key. When hashing the public key with CryptoJS.SHA256 I don't get the expected result

CryptoJS.SHA256("0450863AD64A87AE8A2FE83C1AF1A8403CB53F53E486D8511DAD8A04887E5B23522CD470243453A299FA9E77237716103ABC11A1DF38855ED6F2EE187E9C582BA6").toString(CryptoJS.enc.Hex)

gets me:

32511e82d56dcea68eb774094e25bab0f8bdd9bc1eca1ceeda38c7a43aceddce

while i am trying to get:

600FFE422B4E00731A59557A5CCA46CC183944191006324A447BDB2D98D4B408

Please help

Answer 1

It's just an encoding issue - don't try to hash the hex, hash the binary.

For example, here is the hash computation when you decode the hex into binary (using Haskell since I have it handy):

Prelude> import Crypto.Hash.SHA256
Prelude Crypto.Hash.SHA256> let str = "0450863AD64A87AE8A2FE83C1AF1A8403CB53F53E486D8511DAD8A04887E5B23522CD470243453A299FA9E77237716103ABC11A1DF38855ED6F2EE187E9C582BA6"
Prelude Crypto.Hash.SHA256> Data.ByteString.Base16.encode $ hash $ fst $  Data.ByteString.Base16.decode $ Data.ByteString.Char8.pack str
"600ffe422b4e00731a59557a5cca46cc183944191006324a447bdb2d98d4b408"
