Tool to decrypt/encrypt in Base 26. Base 26 uses 26 symbols, by using the alphabet's letter, one can encrypt words with numbers and conversely.

Encryption uses a simple base 26 conversion using alphabetic characters as symbols

When want to code DCODE, one have to consider that is written in base 26, so can be converted in base 10: D=3, C=2, O=14, D=3, E=4 so \( 3 \times 26^4 + 2 \times 26^3 + 14 \times 26^2 + 3 \times 26^1 + 4 \times 26^0 = 1415626 \)

Decryption consists in converting base 10 to base 26 (using the 26 characters of the alphabet as symbols).

\( 1415626 = 3 \times 26^4 + 2 \times 26^3 + 14 \times 26^2 + 3 \times 26^1 + 4 \times 26^0 \) so [3,2,14,3,4] in base 26 and 3=D, 2=C, 14=O, 3=D, 4=E. The original plain text is DCODE.

The ciphered message is made of numbers, relatively big (for long words)

Usual word can appears multiple times with the same value in a long text.

Rather than converting normally, the word can be considered backward :

DCODE = 3*26^0+2*26^1+14*26^2+3*26^3+4*26^4 = 1890151

as A is encoded 0 in base 26, when encoding it is null and disappear when decoding.

AB = 0*26^1+1*26^0 = 1 and 1 = B

One can add a zero at the beginning of a number to denote a A.
