XORKey

Summary

User-Defined Function: key uXORKey( string vStrOne, string vStrTwo );

Returns a key that is vStrOne bitwise XOR'd with vStrTwo.

• vStrOne: source key
• vStrTwo: source key

Simple Code:

• LSO: 528 bytes
• MONO: 2048 bytes

key uXORKey( string vStrOne, string vStrTwo ){
    vStrOne = (string)llParseString2List( vStrOne, ["-"], [] );

    string  vStrHex = "0123456789abcdef";
    integer vIdxChr 0xFFFFFFE0; //-- (-32)
    integer vIdxHex;
    do{
