## Answers to Questions

### How to encrypt using Base 26 cipher

The encoding with hexavigesimal uses an arithmetic base change from base 26 to base 10. The words are considered as written in base 26 (with 26 symbols: the 26 letters of the alphabet ABCDEFGHIJKLMNOPQRSTUVWXYZ) and converted to base 10.

Example: To code DCODE, written in base 26, convert it to base 10: D=3, C=2, O=14, D=3, E=4 so $$3 \times 26^4 + 2 \times 26^3 + 14 \times 26^2 + 3 \times 26^1 + 4 \times 26^0 = 1415626$$

This method is the most rigorous mathematically, but can raise problems for encrypting words starting with A (which corresponds to the 0 symbol in base 10) and is thus generally ignored at the beginning of the number (001 = 1).

### How to decrypt Base 26 cipher

Hexavigesimal decryption consists of the conversion from the base 10 to the base 26 (using the words as hexavigesimal numbers with the 26 letters of the alphabet as base symbols).

Example: $$1415626 = 3 \times 26^4 + 2 \times 26^3 + 14 \times 26^2 + 3 \times 26^1 + 4 \times 26^0$$ so [3,2,14,3,4] in base 26 and 3=D, 2=C, 14=O, 3=D, 4=E. The plain message is DCODE.

### How to recognize a Base 26 ciphertext?

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 letters option?

Rather than converting normally, the reverse order of letters can be considered (or the word reversed):

Example: DCODE = $$3 \times 26^0 + 2 \times 26^1 + 14 \times 26^2 + 3 \times 26^3 + 4 \times 26^4 = 1890151$$ (this is equivalent to coding EDOCD).

### How to deal with messages starting with 'A'?

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

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

Add a zero at the beginning of a number to indicate a A at the beginning of a word.
