Encoding Text

Encryption is basically like putting a lock on your bike to stop or at least deter people from taking it. If you had a simple 1-2-3-4 combination on your lock, then it would do little to stop theft so if you had a simple cipher then the same would also be true. One example of a recommended strong cipher is the “Advanced Encryption Standard” or A.E.S with 256-bit keys.

The Caesar cipher was an encrypting tool that has been used for a long time and is named after Julius Caesar who used it to encrypt messages of military significance. The Caesar cipher is made up of two rings, the outer ring to show the letter that is uses to hide the actual letter and the middle ring which is the letter your trying to encrypt How it works is you start with a key, the key can be decided by the person writing it but it cannot change, so the person writing the encrypted message must inform the person receiving the message the encrypted code. The code works like this:

K=a which means the outer ring “K” is aligned with the letter “a” on the inner ring

J=u which means the outer ring “J” is aligned with the letter “u” on the inner ring

And

F=p which means the outer ring “F” is aligned with the letter “p” on the inner ring

If you haven’t noticed already the capital letter in the coding the letter ring on the outside and the lower-case letter in the letter ring on the inside, this is probably to try and reduce confusion so the person encrypting it isn’t intending it to be read like g=h and the person decrypting it reads it as h=g.

Caesar Cipher is usually easily shown as two rings and that’s how I have described the Caesar cipher in this but that’s in a physical form, in coding you can have it.
