RACHUS 0.1.0

A custom encryption library that compresses data

ARCHUS

A custom encryption library that compresses data by mapping every 2 bits to a single character, effectively reducing the size of the binary representation.

Installation

You can install the package via pip:

pip install rachus

Usage

Encrypting Text

To encrypt a text string, use the encrypt_text function from the RACHUS package. This function returns the original binary representation of the text and the encrypted string.

from rachus import encrypt_text

s = "he"
binary_text, encrypted_text = encrypt_text(s, r=3)
print(f"Original text: {s}")
print(f"Original binary: {binary_text}")
print(f"Encrypted custom: {encrypted_text}")

Decrypting Text

To decrypt an encrypted string, use the decrypt_text function from the RACHUS package. This function returns the binary representation of the encrypted text and the decrypted original text.

from rachus import decrypt_text

encrypted_text = '1!"#$'
binary_text, decrypted_text = decrypt_text(encrypted_text, r=3)
print(f"Encrypted text: {encrypted_text}")
print(f"Decrypted binary: {binary_text}")
print(f"Decrypted text: {decrypted_text}")

How It Works

Encryption

1. Text to Binary Conversion: The text is converted to its binary representation. Permutation: The binary string is permuted randomly multiple times. Mapping: Each pair of bits is mapped to a specific character according to a predefined mapping.

2. Permutation: The binary string is permuted randomly multiple times.

3. Mapping: Each pair of bits is mapped to a specific character according to a predefined mapping.

Decryption

1. Reverse Mapping: Each character in the encrypted string is mapped back to its original pair of bits.

2. Reverse Permutation: The binary string is permuted back to its original order (assuming the same permutation was used in reverse).

3. Binary to Text Conversion: The binary string is converted back to the original text.
