Is it that large keys are factors of very large prime numbers so that to know the keys you will need a very powerful computer?
- chrisseaton 5y agoXOR with a one-time pad doesn't work off factors of large numbers - you're thinking of asymmetric encryption there. You literally just XOR each plain text byte with a key byte.
- markus_zhang 5y agoThanks! I don't know much about cryptography and will check this out.
- ncmncm 5y agoThere are only two factors of any prime number, large or otherwise: 1 and the number. But even correcting to what you must have meant to suggest doesn't make sense.
