Post Quantum Secure Chat vs FaradayWire Messenger

Secure messaging for the quantum era. PQC Chat is the first consumer messaging app built with NIST-standardized post-quantum cryptography. While traditional encryption may be vulnerable to future quantum computers, PQC Chat uses ML-KEM-768 and ML-DSA-44 algorithms to ensure your private conversations remain private — today and tomorrow. Why Post-Quantum Security Matters Quantum computers pose a real threat to current encryption standards. Data encrypted today could be stored and decrypted later when quantum computers become powerful enough. PQC Chat protects you against this "harvest now, decrypt later" threat. Key Features • True End-to-End Encryption — Messages are encrypted on your device and can only be read by the intended recipient. Not even we can access your conversations. • NIST-Approved Algorithms — Built with ML-KEM-768 for key exchange and ML-DSA-44 for digital signatures, the same standards adopted by governments worldwide. • Secure Image Sharing — Photos are encrypted before leaving your device, ensuring complete privacy for all shared media. • QR Code Contact Verification — Verify contacts in person by scanning QR codes, preventing man-in-the-middle attacks. • Real-Time Messaging — Instant message delivery with read receipts and typing indicators. • No Phone Number Required — Create an account without sharing personal information. • Cross-Platform — Message friends on any device seamlessly. Privacy by Design - No message content stored on servers - No tracking or analytics - No ads, ever - Open cryptographic standards About Post-Quantum Cryptography PQC Chat implements the Federal Information Processing Standards (FIPS) 203 and 204, published by the National Institute of Standards and Technology (NIST) in August 2024. These represent the gold standard in quantum-resistant cryptography. Protect your conversations for the future. Download PQC Chat today. Terms of Use (EULA): https://pqcnow.com/terms-of-service

FaradayWire is a secure messaging app created from the ground up to protect your privacy. By combining modern encryption with hardware-backed security, it’s designed to put you in control of your conversations. Every message is end-to-end encrypted using AES-256-GCM with a unique per-message key. That key is securely encrypted using modern public-key cryptography—either elliptic-curve encryption or RSA—so only you and your intended recipient can read the message. Unlike traditional messaging apps, FaradayWire integrates with YubiKey hardware security keys, ensuring your private keys stay off the cloud and off your phone. For users without a YubiKey, FaradayWire also supports generating and storing private keys securely on the device. --- Hardware Requirements (if using a YubiKey) - Works out-of-the-box with any YubiKey 5 Series (e.g., 5C NFC, 5 NFC, 5C, 5Ci). - iPhone compatibility: NFC and USB-C connections are supported on compatible devices; Lightning requires a YubiKey 5Ci. Using a New vs. Used YubiKey - New key: Plug in or tap to set up—no extra steps. - Used key: If the key is already used by another app’s PIV Key Management slot (9d), you’ll be asked to create a fresh key for FaradayWire. This replaces any existing 9d key on that YubiKey. If you need to keep the old one, use a different slot/key. Technical Details - FaradayWire uses the YubiKey PIV applet, generating an RSA-2048 key in slot 9d for message decryption. - When decrypting on iPhone without a YubiKey, FaradayWire uses elliptic-curve keys and ECIES-based encryption to protect message keys. - Current version supports the default PIV PIN; custom PINs will be supported soon. - Ports: USB-C (iPhone 15+), Lightning via 5Ci, and NFC where available. Features - True end-to-end encryption — Messages and photos are encrypted before they leave your device and only the recipient can decrypt them. - YubiKey integration — Hardware-backed key management keeps private keys off the cloud and off your device. - Option to use secure local device private key storage if not using a YubiKey. - Physical message decryption — Decrypt messages directly with your YubiKey. - Message Re-Encryption — Messages are re-encrypted after returning to the main conversations page. - Simple, immersive experience — A sleek, Matrix-inspired interface that stays intuitive. - Privacy by design — No ads, no data mining, no unnecessary tracking. - Fast & reliable — Built on modern infrastructure for seamless delivery and sync. FaradayWire is inspired by Michael Faraday’s work in shielding against unwanted interference. Like a Faraday cage blocks outside signals, FaradayWire helps shield your conversations from prying eyes.
