[Cryptography] XORing plaintext with ciphertext

2013-09-07 Thread Dave Horsfall
Got a question that's been bothering me for a whlie, but it's likely purely academic. Take the plaintext and the ciphertext, and XOR them together. Does the result reveal anything about the key or the painttext? -- Dave ___ The cryptography mailing

Thanks for the response; that's what I thought, but thought I'd better ask (I'm still new at this crypto game). -- Dave ___ The cryptography mailing list cryptography@metzdowd.com http://www.metzdowd.com/mailman/listinfo/cryptography

[Cryptography] Radioactive random numbers

2013-09-11 Thread Dave Horsfall
Another whacky idea... Given that there is One True Source of randomness to wit radioactive emission, has anyone considered playing with old smoke detectors? The ionising types are being phased out in favour of optical (at least in Australia) so there must be heaps of them lying around. I
