Anyhide - Hide Anything in Anything

Hide anything inside anything. Anyhide is an advanced steganography and encryption tool that conceals any data (text, files, binaries) within any carrier file(s) using hybrid encryption with forward secrecy and plausible deniability.

Why Anyhide?

How It Works

Both parties share a file (ANY file). The sender hides data by finding byte patterns in the carrier. Only an encrypted code is transmitted - the carrier is never sent.

│                                                             │
│  The carrier is NEVER transmitted                           │

Key Features

• Any carrier: text, images, audio, video, PDFs, executables, archives
• Any payload: text messages, binary files, documents, archives
• Dual-layer encryption: Symmetric (ChaCha20) + Asymmetric (X25519)
• Forward secrecy ratchet: Key rotation per message
• P2P Chat over Tor: Real-time encrypted chat via Tor hidden services
• Duress password: Two messages, two passphrases - reveal the decoy under coercion
• Multi-carrier encoding: Multiple files as carrier, order is an additional secret
• Message signing: Ed25519 signatures for sender authentication
• Code splitting: Split codes for multi-channel delivery
• QR code support: Share codes via QR
• Plausible deniability: Wrong passphrase returns garbage, not an error
• Never fails: Decoder always returns something - prevents brute-force detection

Installation

From crates.io:

cargo install anyhide

Pre-built binary: Download from GitHub Releases (Linux, macOS, Windows)

From source:

git clone https://github.com/matutetandil/anyhide.git && cd anyhide && cargo build --release

Quick Start

# Generate keys
anyhide keygen -o mykeys

# Encode a message
anyhide encode -c carrier.txt -m "secret" -p "pass123" --their-key recipient.pub

# Decode a message
anyhide decode --code "AwNhYm..." -c carrier.txt -p "pass123" --my-key recipient.key
