Answers to Questions

How to encrypt using K7 cipher?

K-Seven Encryption is a variant of A1Z26 alphabetical position cipher, but instead of associating A=1, the code uses K=7, and so on, L=8, M=9 etc.

Example: DCODE is coded 26.25.11.26.1

How to decrypt K7 cipher?

K-7 Decryption is also identical to alphabetical rank cipher and requires to know the letter-number association other than 7=K.

How to recognize K7 code ciphertext?

The message is composed of numbers, usually between 1 and 26.

Theorically, the message will have more 1 that represents the letter E by default.

Any reference to the French word Cassette (VHS) or the K-7 mountain is a clue.

What are the variants of the K7 code?

If K=7 is invariant how to number other letters can be different from one method to another. Numbers may be increasing (J=6,K=7,L=8) or decreasing J=8,K=7,L=6 and may become negative or calculated modulo 26.
