At some point in the thread the author complains that it isn't fair to point out the repetitive patterns "because the clear-text is all zeroes and this would be masked by actual data"
- jschwartzi 7y agoMy first thought was "what if I wanted to encrypt and transmit all-zeroes as a message?"
- sidewndr46 7y agoSo the author tried to encrypt the null byte, repeated thousands of times? That seems like the most pointless test I could dream up for any processing algorithm. Computes all the primes less than 0? Already. Achieve compression approaching 100% on a string of zeroes? Easy. Losslessly compress an image with all pixels having opacity of 0? Easy
- RL_Quine 7y agoIt’s a good demonstration of failure that might otherwise be masked
- henrikschroder 7y agoIf an all-null message results in a simple/repeating ciphertext, it means that there exists at least one message whose ciphertext leaks information, and that in turns means that there are probably more messages like it, and it's also probable that all messages leak info in varying degrees.
- nkrisc 7y agoWhat good is encryption that only works for some inputs?
