Description

Encroval is an encryption tool that allows you to encrypt a text into other text or image using a password.

It can encrypt a text of any length and the password can be up to 2¹²⁸ bits long and accepts any UTF-8 character (1,112,064 different characters).

Get Started

Install Requirements

pip3 install -r requirements.txt

Enter the input

Select the text to encrypt

Place the text you want to encrypt (a .txt file) in the input folder.

Select the text/image to decrypt

Place the text you want to encrypt (a .txt file) or the image (a .png file) in the input folder.

Run

python3 main.py

Configuration

You can change the POS_LEN in the config.py file, which changes the input text's maximum length.

Default is POS_LEN = 4, so the maximum length the text can have by default is 32,446

The more the POS_LEN is, the longer the text can be, but the longer it will take to encrypt and decrypt it.

POS_LEN	Max text lenght
1	2
2	107
3	2,026
4	32,446
5	524,169
6	8,386,749
7	134,188,028
8	2,147,329,544
...	...
