A Caesar cipher shifts each letter by a number of letters. For example, if you shift the letter a by three, then you get the letter d, and so on. If the shift goes beyond the end of the alphabet, then you just need to rotate back to the beginning of the alphabet. In the case ...

This algorithm allows for basic text encryption by shifting the alphabet by a number of letters. For example, if you shift the letter a by three, then you get the letter d, and so on.The following code implements cipher(), a function that takes a character and rotates it by three:...
under each letter of the ciphertext, the entire alphabet is written out in reverse starting at that letter. This attack can be accelerated using a set of strips prepared with the alphabet written down in reverse order. The strips are then aligned to form the ciphertext along one row, and ...
A Foolish Consistency is the Hobgoblin of Little Minds (意译)不要硬套本文的编码风格,不动脑子去保持一致性是愚蠢的 One of Guido’s key insights is that code is read much more often than it is written. The guidelines provided here are intended to improve the readability of code and make it...
