in thread How secure is XOR encryption?

>in fact one stream of text XORed with itself Is this a typo? If so, why do you repeat the same mistake several times? Do you just not have a clue? 0 XOR 0 = 0. 1 XOR 1 = 0. Thus any bit string, XORed with itself, is a string of 0 bits as long as the input string. MVP my ass... Dag Johansen

    (And in fact one stream of text XORed with itself has just 1 bit per byte.)
    Yep, Dag, you're right when you say "Thus any bit string, XORed with itself, is a string of 0 bits as long as the input string."

    Therefore, it has one bit per byte.

    Perhaps you missed the part about shifting the string...

    I'm sorry if you believe an XOR "encryption" scheme is meaningful. Cryptography experts disagree.
