ROT Converter

A library for the ROT cipher with multi-language support.

Features

• Encryption and decryption with ROT for 20 languages.
• ROT bruteforce for all supported alphabets.
• CLI Mode.
• Custom Alphabets For The ROT.
• Error handling with clear messages.

Installation

pip install rot-converter

Usage

Import the functions:

from rot_converter import m_rot, b_rot

Manual ROT — m_rot(string: str, key: int, language: str)

Shifts each letter in the string by the given key within the specified alphabet.

from rot_converter import m_rot

temp_str = "tqv_eqpxgtvgt"
new_str = m_rot(temp_str, -2, "en")

print(new_str)  # Output: rot_converter

Bruteforce ROT — b_rot(string: str, language: str)

Returns a list of all possible ROT shifts for the given string.

from rot_converter import b_rot

temp_str = "bcd"
results = b_rot(temp_str, "en")

print(results[24])  # Output: zab
print(results[25])  # Output: abc

Custom Alphabet — m_rot(string: str, key: int, custom_alphabet: str)

Use your own alphabet for encryption/decryption.

from rot_converter import m_rot

# Base-36 alphabet
alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"
result = m_rot("HELLO", 5, alphabet)
print(result)

CLI Usage

After installation, the rot-converter command is available in your terminal.
