Intro to Encryption

Posted by CmdrTaco on from the getting-on-the-same-page dept.

An anonymous reader submitted a Techworld story which is a sort of encryption primer. The difference between codes & cyphers, and what all those acronyms like RSA and DES actually mean. This is good primer material for newbs, and a good refresher for fogeys.

      Nope...Double, or better yet, quadruple rot13 are the greatest...

    That's easy. Code is what I stare at all day, while Cypher is the jerk who betrayed Neo in The Matrix. Duh.

  4. Safe encryption by darkstream · · Score: 5, Funny

    When I want to email with a new friend using PGP encryption, I send him my key one character at a time via snail mail using newspaper clippings. The only time this becomes a problem is when the post office laps itself and delivers more than one letter a day, or gets an earlier letter there later than a later letter, but it's the only way to be sure the key never falls into enemy hands. Of course, I don't get to email many people these days...

    Sometimes that's not good enough. In such instances, I always rot-13 it two times for twice the security.

    1) Get 600MB of random noise data from listening for extra terrestrials from for instance SETI.
    Don't do it!!! Simply, it's not safe. What if you take signal from some extraterestial inteligent species? That signal will not be completely random, and someone will be able to break it...
