You are wrong. Not just slightly, but badly enough that I
could not in good conscience ever recommend you for any
programming job until I was convinced that you had learned
from your mistakes.
I leave it as an exercise for you to read Applied
Cryptography and figure out how to crack your own
scrambling algorithm. A hint. If you xor 20 times it is
the same as having done one xor. (Albeit against a
different key than any of your original 20.) So it does
not matter how well you have managed to confuse yourself
about what you have done, to an attacker this is an xor,
and if they get 2 messages written in English encrypted
this way, they are going to have little trouble reading
both of them.
Just because you don't see how they can do it, doesn't mean
that they can't. Or even that they will find it
particularly hard. | [reply] |
This is no simple XOR algorithm. It is a double cipher XOR algorithm that uses a sophisticated method to alter a given root key. From a given set of random values, there is no way of knowing the number of values inserted into the modified key.
I bet a spook could crack this with less than 1K of known plaintext. "double XOR" is
just reducible to XOR. And as tilly already said, XOR is "seekret decoder ring" stuff.
Your code is worthless to me, and worthless to anyone I have influence on. And that's a pretty large set of the audience here. Please stop bragging -- it merely makes you look more foolish on each round.

Hey Merlyn.
I respect you. You know your stuff, no doubt about it. You even helped me get a better job, by turning me on to Perl with your book.
But hey! You're not supposed to say things like this! First off, you shouldn't be exerting your "influence" on others : let them make their own mistakes and learn from them,
just like you did I'm guessing. You say Steeeve is bragging, but you're claiming you have an influence on "a large set of the audience" at PerlMonks. Now who's bragging?
Ok this is a stupid post from me and I expect to be downvoted for it. Off-topic etc, but let's chill out a bit. And really, your post seems to me like you're asking anyone who likes you on PM to dislike and downvote Steeve, and I don't like that.
my 2 cents, which may or may not make any sense once I hit preview...

Forgive me for asking (or don't...either way), but where's the Perl content in this post? Perhaps you got lost on the way to http://www.javamonks.org?
