duh on my part, yes you are correct, the OS did just previously ask for the current password. It must temporarily persist the current password in memory before requesting the new password and then performs the difference checks using plain-text.

I reworded the title question to better reflect the cryptography related question that I'm trying to get answered.

Hi @e-sushi, perhaps the wording of my question could be better. My question is trying to answer whether it is possible to tell the number of different characters changed between two passwords when only one-way hashing is being used.
