CypherKit

A Python library that helps you secure your data - encrypt files, protect passwords, send secret messages, and hide text in images.

Features

• Password Management: Hash passwords securely with PBKDF2, verify passwords, and generate random passwords
• File Encryption: Encrypt/decrypt files using AES-256-GCM with password-based key derivation
• Message Encryption: Encrypt text messages with AES-256-GCM encryption
• Data Hashing: Generate and verify SHA-256 hashes for data integrity
• Steganography: Hide secret messages inside images using LSB technique

Installation

pip install cypherkit

Quick Start

Password Management

from cypherkit import hash_password, verify_password, generate_password

# Hash a password
hashed = hash_password("my_password")
print(verify_password(hashed, "my_password"))  # True

# Generate random password
password = generate_password(16)
print(password)

File Encryption

from cypherkit import encrypt_file, decrypt_file

# Encrypt and decrypt files
encrypt_file('document.txt', 'password123')
decrypt_file('document.txt.enc', 'password123')

Message Encryption

from cypherkit import encrypt_message, decrypt_message
import os

key = os.urandom(32)  # 256-bit key
encrypted = encrypt_message("Secret message", key)
decrypted = decrypt_message(encrypted, key)
print(decrypted)

Hide Messages in Images

from cypherkit import encode_message, decode_message

# Hide message in image
encode_message('photo.png', 'Hidden message', 'output.png')

# Extract hidden message
message = decode_message('output.png')
print(message)

Requirements

• Python 3.7+
• pycryptodome
• Pillow

Security

• PBKDF2 password hashing with 100,000 iterations
• AES-256-GCM encryption for files and messages
• Cryptographically secure random generation
• Automatic salt generation for password protection
