With current technology we estimate it would take a few quadrillion years to crack 2048-bit encryption. A capable quantum computer could conceivably do it in months. The industry simply can’t afford to play catch-up in the post-quantum age. If we don’t get ahead of the technology now, we may never close the gap.
There’s no set timeline for when a stable computer capable of cracking current encryption algorithms will be realized, but most assume it will be within seven to ten years. Based on the potential threat it poses, and the rapid advances being made in the field, we have to assume it will be sooner.
DigiCert is playing a major role in several PQC initiatives, including the NIST post-quantum cryptography project. To help organizations take advantage of our R&D—as well as to help speed up the process—we’ve developed a PQC Toolkit to allow users to try out hybrid RSA/PQC certificates.
