What is the difference between a stream cipher and a one-time-pad? The one-time pad and Venona project articles say that the USSR and a few other organizations heavily used physical pads of random-looking letters called one-time pads. I think it's pretty likely that practically all of those pads were, in fact, generated with a 100% physical RNG, although I don't really have any evidence one way or another. I suspect that we may never know exactly how those pads were generated. |

How do I calculate CRC32 mathematically? Does "A Painless Guide to CRC Error Detection Algorithms" help? |

Is there a simple hash function that one can compute without a computer? Variation: In addition to forcing every entry in the input column to be unique, also force every entry in the output column to be unique. I.e.: After writing new input on the paper, flip a quarter 8 times, writing the output on scratch paper. If the scratch 8-bit output pattern is already in the output column, to prevent collisions, repeat flipping the quarter 8 more times. When you eventually get a scratch 8-bit output pattern not already in the output column, copy it to the output column. Alas, this variant is awkward for more than 128 unique inputs, and fails after 256. |

Is this design of client side encryption secure? @AndreyBotalov: It's pretty tedious to "review" (or to ask "others" to review) a JavaScript application that could potentially be different every time it is downloaded from the server, potentially downloaded several times per user per day. Is there a good way to at least check if the version of the app I downloaded today is the same as the version I and others previously reviewed yesterday? |
