String ro encode. |
Original encoded string.
XorEncode encodes the string Source by XOR-ing each character in Source with the corresponding character in Key (repeating Key as often as necessary) and representing the resulting ASCII code as a hexadecimal number (of length 2). The result is therefore twice as long as the original string, and every 2 bytes represent an ASCII code.
Feeding the resulting string with the same key Key to the XorDecode function will result in the original Source string.
This function can be used e.g. to trivially encode a password in a configuration file.
None.
