StegVoice
Steganography tool that hides AES-256-GCM encrypted data within Ogg/Opus audio streams.
Python Cryptography 2025
StegVoice embeds encrypted payloads into Ogg/Opus audio files using AES-256-GCM for authenticated encryption. The tool manipulates the Opus codec’s least significant bits to store hidden data while maintaining audio quality that is indistinguishable from the original to human listeners.
Built as a school olympiad project exploring the intersection of cryptography and audio signal processing.
