When will quantum computers break my web app's encryption?

10-20 years for RSA-2048, but HNDL means *now* for high-value targets. Casual apps? Decades out.

What is post-quantum cryptography for developers?

NIST-approved algos like ML-KEM/ML-DSA replacing RSA. Hybrids in browsers today—updates handle most.

Should I replace RSA in my Node.js app now?

If data lasts years, yes—switch signatures to EdDSA, encrypt AES. Short tokens? Wait for stack updates.

Quantum Lockpick: When Web Devs Must Ditch RSA Before Hackers Decrypt 2025's Secrets

Imagine a lockpick trying every key at once. That's quantum computing eyeing your RSA encryption. Web devs: it's not tomorrow's problem—it's 'harvest now, decrypt later.'
