Stegcloak
Stegcloak is a unicode steganography library and text-based data concealment tool. It provides a toolkit for hiding encrypted, compressed secret messages within standard text strings by mapping binary data to invisible, non-printing Unicode characters.
The project combines a symmetric encryption toolkit with an invisible character encoder to ensure secure data concealment. It utilizes password-based key stretching and authenticated symmetric encryption to protect hidden payloads from unauthorized access and tampering.
The system covers the full steganography workflow, including payload compression to minimize the data footprint, secure data hiding within cover text, and the subsequent extraction and decryption of the hidden information.
Features
- Invisible Unicode Mappings - Provides a mapping system that encodes binary data into invisible Unicode characters to hide messages within text.
- Invisible Character Mappings - Provides an encoder that maps binary data to non-printing Unicode characters for covert communication.
- Text-Based Steganographic Extraction - Decodes invisible Unicode characters and decrypts payloads to retrieve secret messages from cover strings.
- Authenticated Encryption - Implements authenticated encryption to ensure both the confidentiality and integrity of the hidden payloads.
- Payload Encryptions - Protects embedded data using strong encryption and integrity checks to prevent unauthorized access or tampering.
- Password-Derived Key Generation - Uses multi-stage key derivation from user passwords to protect encrypted data against brute-force attacks.
- Steganographic Data Hiding - Combines symmetric encryption with steganographic encoding to conceal sensitive data within text.
- Steganographic Payload Extraction - Provides utilities to extract and decrypt secret information embedded within text strings using a password.
- Symmetric Encryption - Employs symmetric encryption and decryption processes using a shared secret key to retrieve hidden messages.
