QuantumPass

Read full description

QuantumPass brings two worlds together: a password and key generator, and a small lab to discover quantum randomness. GENERATE • Passwords from 8 to 64 characters: lowercase, uppercase, digits, symbols, ambiguous-character exclusion, forbidden characters and required characters. The estimated entropy is shown with each result. • Diceware passphrases of 3 to 10 words, in French or English depending on the app language, with the separator of your choice. Strengthen a phrase with randomly drawn capitals, substitutions and suffix. • QRNG: 1 to 100 random bits, in binary, decimal, hexadecimal or Base64. • Blockchain RNG: 128 to 512-bit values in Hex, Base64 or Base58, for your keys and seeds. • All these values come from Apple's cryptographic generator. UNDERSTAND • BB84 demo: follow the key exchange between Alice and Bob, and watch Eve the eavesdropper given away by the error rate. • Qubit Lab: measure a simulated qubit in the Z or X basis and watch the statistics build up. • Bloch sphere: set the θ angle and compare theoretical probabilities with measured frequencies. • Reproducible mode: a seed to replay the same demonstration, in class or in a workshop. • PRNG vs TRNG: two animated panels to see the difference between simulated and hardware randomness. • Built-in tutorial and a 10-question quiz. PRACTICAL • Secure clipboard: whatever you copy stays on the device and is cleared after 60 seconds. • In French and English, on iPhone, iPad and Mac. • Tip Jar: support development right from the app. PRIVACY QuantumPass works offline. All calculations are performed on your device. No account, no ads, no data collected. QuantumPass is an educational tool: its "quantum generator" is a simulation, fed by the system's secure random source.

TruCrypt is encrypted messaging built so that no one but you and the person you're talking to can read a word — not hackers, not us, not anyone who asks. Every message gets its own unique encryption key. Your private key is generated on your device and never leaves it. There's no master key, no backdoor — TruCrypt physically cannot decrypt your conversations. WHAT YOU CAN DO • Send encrypted text, voice notes, photos, videos, and documents in one-on-one conversations — no SMS/MMS exposure, no message limits • Store sensitive files in an encrypted Vault that lives only on your device — never uploaded, never in our reach • Set messages to disappear automatically when a conversation calls for it • Verify who you're really talking to with safety-number verification • Back up your key with a password only you know, so losing your phone doesn't mean losing your history • Real lock-screen previews — still end-to-end encrypted, so your notifications never touch a readable message on our servers CREATOR UPGRADE (OPTIONAL) • Create group Rooms to message multiple people at once • Turn on Stealth Mode to keep your profile out of search and contact discovery entirely WHY IT'S DIFFERENT TruCrypt ships with zero analytics or tracking SDKs — we don't watch how you use the app any more than we can read what you send in it. No ads, no data monetization, no compromises. Built for anyone who needs real confidentiality: individuals, professionals, and anyone with something worth protecting.
