# K6 Code

## K6 Encoder

 Variant K=6, L=7, M=8, ..., Z=21, A=22, B=23, ..., E=26, F=1, G=2, ..., J=5 K=6, L=7, M=8, ..., Z=21, A=-4, B=-3, ..., E=0, F=1, G=2, ..., J=5 K=6, L=5, M=4, ..., P=1, Q=26, R=25, ..., Z=17, A=16, B=15, ..., J=7 K=6, L=5, M=4, ..., P=1, Q=0, R=-1, ..., Z=-9, A=16, B=15, ..., J=7

### How to encrypt using K6 cipher?

K-Six Encryption is a particular case of the A1Z26 alphabetical rank cipher, but rather than associating A=1, the code uses K=6 and so on: L=7,M=8 etc.

Example: DCODE is coded 25/24/10/25/26

### How to decrypt K6 cipher?

K-6 Decryption associates to numbers a letter (it's the opposite of encryption) and requires to know letters-numbers association other than 6=K (often 7=L,8=M etc.)

### How to recognize K6 ciphertext?

A K6 coded message is composed of numbers, often between 1 and 26, and often there is a lot of 26 representing the letter E.

Any reference to the French city of Cassis, the fruit of the cassissier, or the mountain K6 are clues.

### What are the variants of the K6 code?

If K=6 is an invariant, the way to give a number to the other 25 letters can differ. Numbers may be increasing (J=5,K=6,L=7) or decreasing J=7,K=6,L=5 and may become negative or calculated modulo 26.
