PyCryptid

PyCryptid is a Python library for encrypt and decrypt object, text, or image

Installation

pip install cryptid

Usage Examples

Cryptid

This class can encrypt most of python object to bytes and decrypt it back to python object (using pickle)

from cryptid import Cryptid

password = 'mykey'
# or generate a new one
password = Cryptid.generate_key()

cryptid = Cryptid(password)

# encrypt and decrypt dict
normal_dict = {'name': 'John Doe', 'age': 20}
enc_dict = cryptid.encrypt(normal_dict)
dec_dict = cryptid.decrypt(enc_dict)

print(enc_dict) # encrypted <class 'bytes'>
print(dec_dict) # {'name': 'John Doe', 'age': 20}

# encrypt and decrypt function
enc_func = cryptid.encrypt(print)
dec_func = cryptid.decrypt(enc_func)

print(enc_func) # encrypted <class 'bytes'>
dec_func('John Doe') # John Doe

Cryptext

Encrypt text using AES

from cryptid import Cryptext

cryptext = Cryptext(password)
text = 'Hello World'
enc_text = cryptext.encrypt(text) # encrypted string
dec_text = cryptext.decrypt(enc_text)
print(dec_text) # Hello World

Steganography

Hide secret message in image

from cryptid import Steganography

st = Steganography()
input_image = '/path/to/image.png'
output_image = 'output.png'
message = 'Hello World'

# encode message to image
st.encode(input_image, message, output_image) # True
# or using password to encrypt the message
st.encode(input_image, message, output_image, password)

# decode message from image
original_message = st.decode('output.png')
# or with password
original_message = st.decode('output.png', password)

print(original_message) # Hello World

AudioSteganography

Hide secret message in audio file

from cryptid import AudioSteganography

ast = AudioSteganography()
input_audio = '/path/to/audio.mp3'
output_audio = 'output.mp3'
message = 'Hello World'

# encode message to audio
ast.encode(input_audio, message, output_audio) # True
# or using password to encrypt the message
ast.encode(input_audio, message, output_audio, password)

# decode message from audio
original_message = ast.decode('output.mp3')
# or with password
original_message = ast.decode('output.mp3', password)

print(original_message) # Hello World
