WebSep 4, 2009 · XOR allows you to easily encrypt and decrypt a string, the other logic operations don't. If you have a longer string you can repeat your key until its long enough for example if your string was 1010010011 then you'd simple write your key twice and it would become 1011110111 and XOR it with the new string Here's a wikipedia link on the XOR … WebJul 21, 2024 · An important and useful property of XOR that is widely popular in cryptography is that in case of multiple XORing of numbers (say M numbers), if we know only the M – 1 numbers (one is unknown) along with the XOR result then, we can easily calculate the missing number by XORing the known numbers and the XOR result. This …

WebMay 20, 2011 · @Conor Mancone, Thanks for the feedback. XOR encryption can be 'reverse engineered', so that if you know 2 of the 3 variables (i.e. plaintext, key, ciphertext), you can easily find the third.
