# MareArts Crystal
MareArts Crystal is a Python package for encryption, decryption, and serial key management. It provides a simple interface for generating and validating serial keys, encrypting and decrypting strings and files, and performing date-based operations.
## Installation
Install MareArts Crystal using pip:
```bash
pip install marearts-crystal
```
## Usage
Here's a comprehensive guide on how to use MareArts Crystal:
```python
from marearts_crystal import ma_crystal
# Initialize with a secret key
secret_key = "your_secret_key_here"
skm = ma_crystal(secret_key)
# Generate a serial key
username = "john_doe"
start_date = "2023-07-01"
end_date = "2023-12-31"
serial_key = skm.generate_serial_key(username, start_date, end_date)
print(f"Generated Serial Key: {serial_key}")
# Validate the serial key
validated_start, validated_end = skm.validate_serial_key(username, serial_key)
print(f"Validated Start Date: {validated_start}")
print(f"Validated End Date: {validated_end}")
# Date validation
if skm.validate_date("2024-07-01", "2024-12-31"):
print("Date range is valid")
else:
print("Date range is invalid")
# Get today's date
print("Today's date:", skm.get_today_date())
# Generate end dates
print("Tomorrow:", skm.generate_end_date(0, 0, 1))
print("Next month:", skm.generate_end_date(0, 1, 0))
print("Next year:", skm.generate_end_date(1, 0, 0))
# Try with an invalid key
invalid_result = skm.validate_serial_key(username, "invalid_key")
print(f"Invalid Key Result: {invalid_result}")
invalid_result = skm.validate_serial_key("wrong_name", serial_key)
print(f"Invalid Key Result: {invalid_result}")
# String encryption and decryption
original_string = "Hello, MareArts Crystal!"
encrypted = skm.encrypt_string(original_string)
print(f"Encrypted: {encrypted}")
decrypted = skm.decrypt_string(encrypted)
print(f"Decrypted: {decrypted}")
# Decryption with wrong key
wrong_key = "wrong_secret_key"
wrong_skm = ma_crystal(wrong_key)
wrong_decryption = wrong_skm.decrypt_string(encrypted)
print(f"Decryption with wrong key: {wrong_decryption}")
# File encryption and decryption
input_filename = "example.bin" # This can be any file, binary or text
output_encrypted_filename = "example_encrypted.bin"
# Read and encrypt the file
with open(input_filename, "rb") as file:
file_content = file.read()
encrypted_content = skm.encrypt_data(file_content)
# Save the encrypted content
with open(output_encrypted_filename, "wb") as file:
file.write(encrypted_content)
print(f"File '{input_filename}' has been encrypted and saved as '{output_encrypted_filename}'")
# Decrypt the file
input_encrypted_filename = output_encrypted_filename
output_decrypted_filename = "example_decrypted.bin"
# Read and decrypt the file
with open(input_encrypted_filename, "rb") as file:
encrypted_content = file.read()
decrypted_content = skm.decrypt_data(encrypted_content)
if decrypted_content:
# Save the decrypted content
with open(output_decrypted_filename, "wb") as file:
file.write(decrypted_content)
print(f"File '{input_encrypted_filename}' has been decrypted and saved as '{output_decrypted_filename}'")
else:
print("Decryption failed. The file might be corrupted or the wrong key was used.")
```
