Tool to convert letters to numbers and vice versa. The Letter-to-Number Cipher (or Number-to-Letter Cipher) consists in replaceing each letter by its position in the alphabet, for example A=1, B=2, Z=26.

Decrption requires only to know the used alphabet (usually the latin alphabet with 26 characters).

One has to replace each letter with it's position in the alphabet (A = 1, B = 2, ... Z = 26)

DCODE becomes 4-3-15-4-5.

Decryption requires to take each number and replace it with the letter of same position in the alphabet. 1 = A, 2 = B, ... 26 = Z

1.12.16.8.1.2.5.20 gives ALPHABET.

The crypted message is made of numbers between 1 and 26, sometimes the number 0 is used.

The digit 5 for E is supposed to appear regularly for an english text.

Shift of numbers: the alphabet can start with A = 0 or A = 1, but also A = 65 or A = 97 (ASCII code).

Use of a supplementary character for space (usually 0 or 27)

Use of leading zeros to be able to concatenate numbers AB = 0102, else AB = 12 and 12 = L.

Use of a custom alphabet, or reversed alphabet (A=26, Z=1)

Use of modulo 26 in order to get 1=A,2=B,...26=Z then 27=A, 28=B etc.
