Answers to Questions

How to encrypt using Base 26 cipher

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 26href

By converting in base 10href : D=3, C=2, O=14, D=3, E=4 so 3*26^4 + 2*26^3 + 14*26^2 + 3*26^1 + 4*26^0 = 1415626

How to decrypt Base 26 cipher

Decryption consists in converting base 10 to base 26 but using the 26 characters of the alphabet as symbols

1415626 = 3*26^4 + 2*26^3 + 14*26^2 + 3*26^1 + 4*26^0 = [3, 2, 14, 3, 4] in base 26href and 3=D, 2=C, 14=O, 3=D, 4=E

The original plain text is DCODE.

How to recognize an Base 26 ciphered text?

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.

What is the reverse order option?

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

How to deal with messages starting with 'A'?

as A is encoded 0 in base 26href, 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.
