This is an example of Columnar Transposition Cipher in python. This project uses matrixes to hash a string.
The project requires no dependencies. So getting started is as easy as,
- Clone the repository
- Open the
main.pyfile - Edit the variables under the comments those state which ones to change.
It's an old cipher used in the past. It's really simple.
The plain text will be referred to as "string to hash" from now on.
The string to hash will be "Hello world!" for now. First, we will create a grid with a breadth of 5 characters and length N, and fill it with the characters in the string to hash.
| 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|
| H | E | L | L | O |
| W | O | R | L | |
| D | ! |
The above table is then converted to the hash by just writing the content from bottom to top, so the result will be 'd H!we ol rl lo'.
