About

Nan

This tool captures and decrypts network traffic at the TCP/IP layer, offering advanced features for detecting TLS connections and WebSocket traffic. It allows selective capture of HTTPS traffic to prevent application malfunctions.

Highlights
  • TCP/IP layer capture
  • System proxy bypass
  • TLS connection detection
  • HTTPS capture and decryption
  • WebSocket decryption
  • IP packet assembly

Why You Need This: - Capture on TCP/IP layer, NOT system proxy. Avoid some applications not going through the proxy - Detect TLS connection and ALPN - Only capture and decrypt HTTPS the address you specify, to prevent certain applications from malfunctioning due to addresses that cannot be captured by packet capture. - Also support decrypt WebSocket How it works: - This app captures all IP packets (IP layer) - Next assemble into TCP stream (TCP layer) - Probe TLS connections and ALPN information to help you determine if there's any possibility of packet capture. - Next assemble into HTTPS/WebSocket packet (Application layer) if you MITM it

StealthOps - Invisible Secure Messaging StealthOps is an advanced steganography app that allows you to hide encrypted messages and images inside normal-looking text using cutting-edge zero-width character technology. Your secret communications remain completely invisible to anyone without the proper decryption keys. What It Does StealthOps transforms ordinary text like "Hey, how's your day going? Hope you're doing well!" into the exact same looking text that secretly contains hidden encrypted content. The text appears identical, but contains a hidden encrypted message or image that only the intended recipient can reveal. How It Works Zero-Width Steganography: Uses invisible Unicode characters (zero-width spaces, joiners, etc.) to embed data. The hidden content is completely invisible to the human eye and text appears normal in any messaging app, email, or social media. Can be copied, pasted, and shared like regular text. Military-Grade Encryption: RSA 2048-bit encryption protects all hidden content. Public/Private key pairs ensure only intended recipients can decrypt. Each contact has unique encryption keys for maximum security. Messages are encrypted before being hidden in the text. Dual Contact System: Sender Contacts are people who can send you encrypted messages. Receiver Contacts are people you can send encrypted messages to. Easy QR code sharing for exchanging public keys with automatic key management and validation. Key Features Hidden Text Messages: Encrypt secret text inside innocent-looking messages. Perfect for sensitive communications that need to appear normal. Supports any length of hidden content. Hidden Image Encryption: Hide entire images inside plain text messages. Images are compressed, encrypted, and embedded invisibly. Share photos securely without anyone knowing. Contact Management: Add contacts by scanning QR codes or importing public keys. Visual indicators show contact types with secure key exchange process. Smart Detection: Automatically detects if received text contains hidden content. Identifies whether hidden content is text or images with one-tap decryption and viewing. Modern Interface: Clean, intuitive design with dark mode support. Segmented tabs for sent/received content. Real-time encryption status indicators and haptic feedback. Security Features End-to-End Encryption ensures messages are encrypted on your device before hiding. Zero Knowledge means the app never stores or transmits your private keys. Plausible Deniability makes hidden messages completely undetectable. Forward Secrecy uses unique key pairs for each contact. Tamper Detection safely rejects invalid or corrupted hidden content. How to Use Setup: Add contacts by scanning QR codes or importing public keys. Share your key by generating and sharing your public key via QR code. Verify keys to confirm key exchange with your contacts. Sending: Select a receiver contact, enter your secret message or select an image, add innocent-looking cover text, then encrypt and share the normal-looking text anywhere. Receiving: Paste suspicious text into the decode screen, select the sender contact for decryption, tap decode to reveal hidden content, then view the secret message or image. Privacy & Security No Cloud Storage keeps all data on your device. No Analytics means zero telemetry or user tracking. Offline Capable works without internet connectivity. Secure Deletion properly cleans up sensitive data. StealthOps represents the cutting edge of digital steganography, combining advanced Unicode manipulation techniques, robust cryptographic implementations, user-friendly interface design, and cross-platform text compatibility. The app makes military-grade steganography accessible to everyone while maintaining the highest security standards. StealthOps: Where your secrets become invisible.
