I'm still exploring how to do the Login system in the desktop UI application.

I found this:

https://www.b4x.com/android/forum/threads/password-sha512-hash-and-salt.75011/

I have problems with the Salt function. I get the following error:

I want to create an application in which the user logs in with a user name and password. It requires that the password is in no way possible to be identified or stored as readable text anywhere. As far as I understand, Password SHA512 hash and salt is a good solution for my application.

Does anyone know any other solution, idea?
