stegcore

We have hosted the application stegcore in order to run this application in our online workstations with Wine or directly.

Quick description about stegcore:

Stegcore combines cryptography and steganography to hide encrypted data inside ordinary files. It encrypts your payload before embedding it, so the hidden content is unreadable even if someone extracts it, and invisible to anyone who doesn't know it's there.

Unlike basic steganography tools that hide data without encrypting it, Stegcore ensures the payload is cryptographically protected at rest. Unlike pure encryption tools, the payload isn't even visible.

Designed for journalists, security researchers, red teamers, digital forensics professionals, and CTF participants.

Features:

• Three AEAD ciphers: Ascon-128 (NIST lightweight standard), ChaCha20-Poly1305, and AES-256-GCM
• Argon2id key derivation for passphrase hardening
• Durable against Steganalysis
• Key file support alongside passphrase
• zstd payload compression before embedding
• Standard and Adaptive LSB embedding for PNG and JPEG (pixel-domain)
• Dual interface: CLI and GUI in a single binary
• Native binaries for Windows, Linux, and macOS

Audience: Advanced End Users, Information Technology, Security, Security Professionals, System Administrators.
User interface: Command-line, React.
Programming Language: Rust, TypeScript.
