Expand description
The crate contains the playfair, the two square and the four square cipers. Note all of the are pre computer cipers. Do not feel like protecting data of any value with them. Any of them is crackable in very short time.
When using the method encrypt the payload is converted to uppercase and any character not within the range A..I and K..Z is ignored. E.g. “I would like 4 tins of jam.” becomes “IWOULDLIKETINSOFIAM”. So you don’t need to clear off not encryptable characters when using this library.
