bitcrypt 1.0.0

A library for bit-level encryption and decryption with Base64 encoding.

BitCrypt

BitCrypt is a Python library for encrypting and decrypting text strings at the bit level, with additional Base64 encoding for secure storage or transmission.

Features

• Encrypt strings by inverting their bits and encoding them with Base64.
• Decrypt Base64-encoded strings back to their original form by restoring the inverted bits.
• Simple API for integration into other projects.
• CLI support for quick encryption and decryption.

How It Works

The library performs encryption and decryption through the following steps:

Encryption

1. Input: A plaintext string.
2. Convert to Bytes: The input string is converted to a byte sequence.
3. Invert Bits: Each byte's bits are flipped (using the ~ operator).
4. Base64 Encoding: The inverted bytes are encoded into a Base64 string for portability and security.
5. Output: The resulting Base64 string.

Decryption

1. Input: A Base64-encoded string.
2. Decode from Base64: The string is decoded into its original inverted byte sequence.
3. Restore Bits: The inverted bits are flipped back to their original state.
4. Convert to String: The restored bytes are converted back into a plaintext string.
5. Output: The original string.
