SecuriPy

SecuriPy is a Python library that provides a set of functions for encrypting and decrypting human-readable file formats into undefined non-readable files. It offers a simple yet powerful way to protect sensitive information from unauthorized access.

Installation

To use SecuriPy, you will need Python 3.x installed on your system. You can install SecuriPy using pip, the Python package installer, by executing the following command:

pip install SecuriPy

Usage

Import the classes you need:

from SecuriPy import Text, Image, File, DNA

Text — Password-based obfuscation

Note: The Text class uses a simple additive cipher. It provides obfuscation only and is not cryptographically secure. For strong encryption use File or Image.

from SecuriPy import Text

encrypted = Text.encrypt("Hello World", password="mypassword")
original  = Text.decrypt(encrypted, password="mypassword")
print(original)  # Hello World

Image — Fernet (AES-128) image encryption

from SecuriPy import Image

Image.Key()                                # generates key.txt
Image.Encrypt("key.txt", "photo.png")     # encrypts photo.png in-place
Image.Decrypt("key.txt", "photo.png")     # decrypts back to original

# Encrypt / decrypt everything in the current directory
Image.EncryptAll("key.txt")
Image.DecryptAll("key.txt")

File — Fernet (AES-128) file encryption

from SecuriPy import File

File.Key()                                 # generates key.txt
File.Encrypt("key.txt", "document.pdf")   # encrypts in-place
File.Decrypt("key.txt", "document.pdf")   # decrypts back to original

# Encrypt / decrypt everything in the current directory
File.EncryptAll("key.txt")
File.DecryptAll("key.txt")

DNA — DNA base-sequence encoding

Encodes text as a sequence of DNA bases (A, T, C, G). This is an encoding scheme, not a cryptographic cipher.

from SecuriPy import DNA

encoded  = DNA.encrypt("Hello")   # e.g. 'TACGTATGTA...'
original = DNA.decrypt(encoded)   # 'Hello'

Security Considerations

• Use a strong and unique key for each encryption operation to enhance security.
• Always store your key.txt securely — losing it means losing access to your encrypted data.
• Image and File classes use Fernet symmetric encryption (AES-128-CBC + HMAC-SHA256).
• The Text class is a lightweight obfuscation cipher only.
