Quantum computers will break today's encryption
What Shor's algorithm actually does to your data
RSA and ECC protect your company data today. A quantum computer running Shor's algorithm breaks them in minutes.
Understand what changes - and what breaks.

01 / Where the damage lands
Approximate sector exposure
RSA and ECC, the foundation of almost every digital identity today, can be broken in minutes by a sufficiently powerful quantum computer using Shor's algorithm. This threatens TLS connections, digital signatures, X.509 certificates, OAuth tokens, and every credential built on classical public-key cryptography. Grover's algorithm additionally halves the effective strength of symmetric keys: AES-128 drops to 64-bit security. The threat is not theoretical, it's a matter of engineering timeline.
