About

QuantumPass

Read full description

QuantumPass brings two worlds together: a password and key generator, and a small lab to discover quantum randomness. GENERATE β€’ 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. β€’ 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. β€’ QRNG: 1 to 100 random bits, in binary, decimal, hexadecimal or Base64. β€’ Blockchain RNG: 128 to 512-bit values in Hex, Base64 or Base58, for your keys and seeds. β€’ All these values come from Apple's cryptographic generator. UNDERSTAND β€’ BB84 demo: follow the key exchange between Alice and Bob, and watch Eve the eavesdropper given away by the error rate. β€’ Qubit Lab: measure a simulated qubit in the Z or X basis and watch the statistics build up. β€’ Bloch sphere: set the ΞΈ angle and compare theoretical probabilities with measured frequencies. β€’ Reproducible mode: a seed to replay the same demonstration, in class or in a workshop. β€’ PRNG vs TRNG: two animated panels to see the difference between simulated and hardware randomness. β€’ Built-in tutorial and a 10-question quiz. PRACTICAL β€’ Secure clipboard: whatever you copy stays on the device and is cleared after 60 seconds. β€’ In French and English, on iPhone, iPad and Mac. β€’ 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.
