• Is SHA-256 Case Insensitive? 4 answers

Recently I started to make an UCP for a game server but I come to a problem. The game server hash passwords with sha256 and salt. The hashed password look like this 399B77A0AD470496AE09579C2CA3FAF2F01E8A63D9F4ECFA6F60E32CE2E7E5E9 but the php hash function for sha256 give this hash 399b77a0ad470496ae09579c2ca3faf2f01e8a63d9f4ecfa6f60e32ce2e7e5e9.

When the user input and the password from database it's compared, they are not the same and user can't login.

How to ignore uppercase/lowercase or how to make the hash function to hash the input in uppercase?
