### How to encrypt using letters position cipher?

Encryption is a kind of description of the text to be encoded. The word/string to be encoded is decomposed of characters/letters, the coding consists in indicating, next to each character, its rank/index in the string/word in order to form couples/pairs (letters-position).

Example: The message POSITION is composed of a P in position 1, then an O in position 2 etc. or P1,O2,S3,I4,T5,I6,O7,N8

To encode a secret message, a random mix of couples/pairs is recommended.

### How to decrypt using letters position cipher?

Decryption is a reading of couples (letters,position) and decoding consists of rewriting the characters in their place/number in the string.

Example: B2,C3,A1 stands for B in position 2, C in position 3 and A in position 1 or ABC

### How to recognize a characters' positions ciphertext?

The message is composed of pairs (character,number).

Each number can theoretically appear only once.

### What are the variants of the characters' positions cipher?

Several variations are possible:

- Mix the pairs (the order does not change the decryption)

- Reverse position of positions and letters (letter, position) or (position, letter)

To encode a message according to the position of letters in the alphabet see the code A1Z26.
