Many thanks for AndAlex.

This tool is very helpful to remember a lot of the password for different website accounts.

Would you rewrite the Tool UI?
Please make the "Site" box and "Salt" box in different row, that is easy way to view the long chars.

Another suggestion for user can change the Scrypt Difficulty setings such as 2^10, 2^11 etc. for professional usage.

Last, best wishes for you, the love from the other country.
