For example, the code IBDLBEBZ is encrypted with a Caesar Cipher. It doesn’t take very much to see that a shift of “1” would reveal HACKADAY. This…is not security, and is equivalent to a ...

The arena of creating secure environments in the hardware and software industries is somewhat shrouded in mystery and misunderstanding. Certainly, some types of ciphers are relatively straightforward ...

The key for a cipher used by Augustus Caesar, some 2,000 years ago, was simple enough: The receiver just had to shift the alphabet one position. In other words, "a" was represented by "b," "b" was ...

A few months ago, GeekDad’s Challenge of the Week was a lovely cipher about famous novels beginnings. I enjoyed solving it and that reminded me of a time where I was teaching younger students ...

For example, with a shift of 1, A would be replaced by B, B would become C, and so on. The method is named after Julius Caesar, who apparently used it to communicate with his generals.
