Fixing Cryptography Before It Is Broken

…Ever since Peter Shor showed how a quantum computer could factorize large numbers with exponential speedup, it has been known that quantum computers could become a threat to most cryptographic algorithms currently in use…

…Affected crypto algorithms include, among others, the well-known encryption schemes RSA and ECIES, the digital signature algorithms DSA and ECDSA, and the Diffie-Hellman key agreement…

…In other words: Virtually every protocol in current use that involves a certificate with a public key of some kind is likely to be broken by a quantum computer in the future…
