Ok, I've updated the script to version 1.20. This version allows you to customize the amount of supported characters in the encryption (using /complex and /size) at the cost of the encryption's length. The new complex character set is more than 5 times the size of the original character set, and if set to the correct settings, the encryption can support Asian characters as well.
There is also a save feature so that you don't need to retype your settings every time you log in.
See the first post for details. Any feedback would be
! Thanks!
