The web security landscape is about to change dramatically.

For years, modern cryptography has relied on algorithms like RSA and elliptic-curve cryptography (ECC). They are battle-tested and secure against classical computers — but quantum computing changes the equation entirely.

Once large-scale quantum computers become practical, many of today’s public-key systems will become vulnerable.

That future may still be years away, but encrypted data stolen today can still be decrypted later.

This is why post-quantum cryptography (PQC) matters now.

And yet, if you are a JavaScript or TypeScript developer, the ecosystem for PQC is still surprisingly small.

That’s why I built Paranoia.ts .

What is Paranoia.ts?

Paranoia.ts is a TypeScript-first cryptography library designed for frontend and full-stack applications that need:

End-to-end encryption (E2EE)

Post-quantum resistance

Optimization

The goal is simple:

Make post-quantum encryption practical and accessible for JavaScript…
