In easy steps, this is how it works:
- Convert txt to numbers. mod 1-26.
- Generate random numbers (by my other cipher) equal to plain txt.
- Write random numbers under txt numbers.
Like this:
txt = LOI - txt number = 12 15 09 - random number = 73 96 14
Encryption system, random numbers under txt numbers
12 15 09 --> txt number
73 96 14 --> random number
85 01 13 --> encrypted number
- 1+7=8 , 2+3=5 , 1+9=0 not '10' if the result two digit take the 2nd digit 5+6=1 , and so on.
- If the result two digit '10,11,12,13,...,19' take the second digit '0,1,...,9'
- Last step will convert the numbers to letter and numbers.
Like this:
8 5 0 11 3 --> HE0KC or 8 5 0 1 1 3 --> HE0AAC
- Revers the steps to get the plain text, If the encrypted number smaller than the random number that mean we take the second digit 5+6=1 Reverse 1-6=5 because 5+6=11 2nd digit = 1.
So, is it secure or not?
