What would you like to do?
Decodes a password from HeidiSQL. HeidiSQL passwords can be found in the registry. Use File -> Export Settings to dump all settings. Great for if you forget a password.
function heidiDecode(hex) {
var str = '';
var shift = parseInt(hex.substr(-1));
hex = hex.substr(0, hex.length - 1);
for (var i = 0; i < hex.length; i += 2)
str += String.fromCharCode(parseInt(hex.substr(i, 2), 16) - shift);
return str;
