[Function] - UnicodeCrypter() - Encrypt\Decrypt Unicode (Support All Characters from 1 to 1114111)

[User]

A very simplistic function that Encrypt\Decrypt Unicode characters from 1 to 1114111 (Tested encryption\decryption with all the characters at once and no issues found)!

This function is very simple and clearly aimed for non-advanced users who just don't want to save their plain text data into files without any kind of encryption!

Code: Select all

gui, add, text, , Unicode:
gui, add, edit, w400 h300 +HScroll gEncrypt +HwndEditIdU,
gui, add, text, , Encrypt Key =
gui, add, edit, x+5 w200 vEK gEncrypt, 0|A|6|5|8|E|2|C|1|F|B|D|4|3|9|7		;"0|A|6|5|8|E|2|C|1|F|B|D|4|3|9|7" is the function default key
gui, add, button, x+5 gEK, Generate

gui, add, text, ys, Encrypted:
gui, add, edit, w400 h300 +HScroll gDecrypt +HwndEditIdE,
gui, add, text, , Decrypt Key =
gui, add, edit, x+5 w200 vDK gDecrypt, 0|A|6|5|8|E|2|C|1|F|B|D|4|3|9|7		;"0|A|6|5|8|E|2|C|1|F|B|D|4|3|9|7" is the function default key
gui, add, button, x+5 gDK, Generate

gui, add, text, xm, Since Autohotkey does not support "null" characters, "0" must be the first Hex symbol in "key" in order to prevent issues!
