Reitse Eskens hit an interesting issue:
The issue is quite simple. A text needs to be converted into a SHA2_256 hash for some authentication reasons. The example shown here is simplified. The thing is, the outcome of the hash isn’t accepted by the authorising party and when the input is checked via an online MD5 hashing site, there’s a difference between that output and that from the SQL Script.
Read on to see what the problem is and how it can affect you.
