Pcryption is a pen-and-paper cipher designed to encrypt and decrypt text using nothing but a blank sheet of paper.
The cipher breaks down letters into a 3-digit code block. Every letter is assigned a code based on three columns that cycle sequentially (Column 1 ➔ Column 2 ➔ Column 3 ➔ Column 1...).
Each 3-digit code [X][Y][Z] is structured like this:
X(The Group/Row): Dictated by the column cycle.- Column 1 uses groups
1, 2, 3 - Column 2 uses groups
4, 5, 6 - Column 3 uses groups
7, 8, 9
- Column 1 uses groups
Y(The Slot): The specific position (01through09) inside that block.Z(The Global ID): The raw position of the character in the global 81-character matrix.
Because of this layout, you can easily calculate the codes in your head without looking at the table below.
| Column 1 (Cycle 1) | Column 2 (Cycle 2) | Column 3 (Cycle 3) |
|---|---|---|
| 101 A 1 | 401 A 28 | 701 A 55 |

To encrypt a message, you shift columns for every single letter: Column 1 ➔ Column 2 ➔ Column 3, then restart at Column 1.
Plaintext: Hello I am Chane
Letter: H e l l o [ ] I [ ] C h a n e
Cycle: (1) (2) (3) (1) (2) (3) (1) (2) (3) (1) (2) (3) (1)
Code: 108 405 803 203 506 909 401 609 103 408 701 205 405
I don't mind if you use it of modified it feel free to do anytings with it you don't need to credit me since I many people might have same idea (But you could credit me I'll appreciate it)
Hope you have a great day this is my first repo and hope this use full it probably not be really useful but hey enjoy making it and share here
