QuantumPass

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.
