Tool for decoding / encoding by describing the positions of the letters in a word XYZ = X1, Y2, Z3. A string of characters (a word, a sentence) can be described by indicating the rank of each character.

Answers to Questions (FAQ)
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.
