MusiKey is a cross-platform desktop application that replaces traditional passwords with encrypted musical compositions. Each user's identity is bound to a unique, algorithmically generated song that is encrypted using military-grade cryptography and can only be unlocked with the correct passphrase.
When you enroll, MusiKey generates a one-of-a-kind musical composition constrained to your chosen scale — pentatonic, blues, major, minor, and more. The song is then encrypted using a cascaded key derivation pipeline (PBKDF2 + scrypt) and sealed with double-layer AES-256-GCM encryption. To authenticate, you enter your passphrase. If correct, the song decrypts, passes a four-dimensional musicality analysis, and plays back through an animated piano and frequency visualizer. If incorrect, exponential rate limiting kicks in — and after five failed attempts, the credential self-destructs permanently.
MusiKey employs 15 layers of security including cascaded PBKDF2 (600,000 iterations) and scrypt (128MB memory-hard) key derivation, double AES-256-GCM encryption, encrypted-at-rest credential storage with machine-bound keys, HMAC tamper detection, key splitting across multiple files, passphrase strength enforcement with entropy estimation, credential integrity hashing, automatic memory zeroing, and a self-destruct mechanism that overwrites destroyed credentials with random data.
Features include cross-platform support (Windows, macOS, Linux), 7 musical scales with configurable song length (32-256 notes), real-time passphrase strength meter, live piano keyboard and frequency bar visualizer, four-dimension musicality scoring (harmonic, melodic, rhythmic, scale adherence), credential export/import for backup, zero runtime dependencies — all cryptography via native platform APIs, and dark-themed interface.
The application is built with Electron, TypeScript, Web Crypto API, Web Audio API, and Node.js scrypt.
