Debunking a Bogus Encryption Statement?
deviantphil asks: "Recently, a coworker tried to assert that encrypting a file twice with a 64 bit algorithm is equivalent to encrypting it once with a 128 bit algorithm. I know enough about encryption to know that isn't true, but I am having difficulties explaining why and how. Doesn't each pass of the encryption create a separate file header which makes this assertion untrue? Can anyone point me to references that would better help me explain this?" What other laughable claims have you heard attributed to encryption, and how were you able to properly lay them to rest?
In other words, you don't know what you are talking about, tragicly think you do, have the arrogance to speak with faux authority, and graced us with 5 paragraphs to prove it. Thanks. Clue: W. Diffie & M. Hellman to start, gain clue, show your math. Yours, Kjs3
Dude, for someone who clearly not an authority you sure talk a lot. I hope your day job is selling carts, not programming computers.
