I am new to SHA-256. I have discovered that the same input could produce different SHA-256 hash ouputs depending on the (online) device I chose for generating the hash.
Is this normal, or is there a problem on one of the devices I used?
Edit: If I get it right, there might be an encoding issue that makes it possible to have two different outputs for the same input. .. But, are these two different outputs BOTH valid SHA-256 hashes ? Can I say this, or not ? Or, is one of these two different outputs a "false sha-256" hash? And if yes, how to sort them in order to make sure of using the "real" one?
Thanks for your help!
