The Challenge
Computing 4 different cryptographic hashes in real-time as the user types, without UI lag or blocking the main thread.
The Approach
Leveraged the browser's native Web Crypto API (crypto.subtle.digest) to compute all 4 hash algorithms asynchronously on every keystroke. Results are rendered instantly with click-to-copy functionality.
The Result
An instant, zero-latency cryptographic hash tool used by developers for checksums, data integrity verification, and security testing.
