Tienc 0.0.2

package for encrypting text and images using Hybrid encryption, asymmetric encryption or symmetric encryption.

Tienc

Tienc is a simple library that allows you to encrypt and decrypt text and images Hybrid encryption, additionally tienc allow standalone encryption using either AES encryption or RSA encryption. Tienc is based on the Cryptography library. Tienc contains 3 classes, AESEncryption, RSAEncryption and HybridEncryption.

AESEncryption

AES encryption class with two methods: encrypt and decrypt. encrypt takes data as a parameter and returns the ciphertext. Decrypt takes ciphertext as a parameter and returns the decrypted data.

RSAEncryption

RSA encryption class with two methods: encrypt and decrypt. Encrypt takes data as a parameter and returns the ciphertext. Decrypt takes ciphertext as a parameter and returns the decrypted data.

HybridEncryption

Hybrid encryption class with four methods: encrypt_text, decrypt_text, encrypt_image and decrypt_image. Encrypt_text takes text as a parameter and returns the ciphertext and the encrypted key. Decrypt_text takes ciphertext and encrypted key as parameters and returns the decrypted text. Encrypt_image takes image as a parameter and returns the ciphertext and the encrypted key. Decrypt_image takes ciphertext and encrypted key as parameters and returns the decrypted image.

Installation

Use the package manager pip to install Tienc.

pip install Tienc

Usage

hybrid_encryption = HybridEncryption()

# Encrypt text
ciphertext, encrypted_key = hybrid_encryption.encrypt_text("Hello, World!")

# Decrypt text
plaintext = hybrid_encryption.decrypt_text(ciphertext, encrypted_key)
print(plaintext) # "Hello, World!"

# Encrypt image
encrypted_chunks, encrypted_key = hybrid_encryption.encrypt_image("image.jpg")

# Decrypt image
image = hybrid_encryption.decrypt_image(encrypted_chunks, encrypted_key)

It's important to note that the key used in the AESEncryption class is generated randomly every time the class is instantiated, so the key used to encrypt the data must be stored in a secure location, if needed for future decryption.
