This F5 Labs explainer describes how quantum computing affects cryptography. Shor's algorithm can efficiently break the problems behind RSA, DSA, Diffie-Hellman and ECC, while Grover's algorithm only halves the effective strength of symmetric ciphers such as AES. The article stresses "harvest now, decrypt later" risk: an adversary who rec…
The F5 Labs 2026 State of PQC on the Web report scanned the top 1 million domains with TLS 1.3 handshakes.
