<h3 id="orion4d-secret-agent-steganography-and-encryption-toolkit">🕵️‍♂️ Orion4D Secret Agent - Steganography &amp; Encryption Toolkit</h3>Orion4D Secret Agent is a comprehensive toolkit for ComfyUI dedicated to steganography, encryption, data encoding, and information transmission through audio and visual channels.This node suite allows you to hide, transform, and secure data (text, images, files) within multimedia streams. Whether you want to encode messages into images, convert audio to Base64, or inject workflows directly into image metadata, this is the ultimate spy toolkit for ComfyUI.🌟 Main Features &amp; Node Categories1. Data Converters &amp; Encoders<ul><li>Base64 / Binary / Hex / Decimal: Fully encode and decode text to various formats.</li><li>Audio &amp; Image to Base64: Convert audio streams or images into Base64 strings and vice versa.</li></ul>2. Steganography &amp; Cryptography<ul><li>Audio Crypt &amp; Modem Nodes: Encode data into audio signals (OFDM, Morse, Modem simulation).</li><li>Military &amp; Cipher Nodes: Advanced text and data encryption tools.</li><li>Workflow Injector: Hide a specific ComfyUI JSON workflow directly inside an image's metadata without altering the visual.</li></ul>3. Multimedia &amp; I/O<ul><li>AV Muxer: Create static videos (MP4/AVI) from a single image and an audio file, or replace audio in existing videos.</li><li>Clean Save Image: Save images while stripping all metadata for total privacy.</li><li>Advanced Audio Save: Manage WAV/FLAC/MP3 saving with timestamping and subfolders.</li><li>Text Compression: Compress text (Zlib or LZMA) to Base64 to save space.</li></ul>4. Utility Nodes<ul><li>Simple OCR: Read text contained within an image using Tesseract.</li><li>PDF Report: Generate simple PDF reports combining images and text fields.</li><li>Text Bus (Variables): Define global variables to transport text across your workflow without messy visible links!</li></ul>⚙️ InstallationOpen your terminal in the <code>ComfyUI/custom_nodes/</code> directory and run:Bash<pre><code>git clone https://github.com/orion4d/Orion4D-secret_agent
</code></pre>Then, install the requirements (if any) and restart ComfyUI.🛠️ How to get started?Download the <code>.json</code> files or the demo workflow provided in this Civitai post and load it into your UI. It will guide you through the basic concepts of encoding and decoding data.🔗 Links &amp; Support<ul><li>GitHub Repository: <a target="_blank" rel="ugc" href="https://github.com/orion4d/Orion4D-secret_agent">https://github.com/orion4d/Orion4D-secret_agent</a></li><li>If you enjoy this project and find it useful, please consider giving it a ⭐ on GitHub and supporting the creator on Ko-fi!</li></ul>
