About

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.
