Translations:SSH security improvements/2/en

With constant increase in computing power over time, some encryption algorithms and protocols which were reasonably secure ten or fifteen years ago now pose an unacceptable risk of the connection being compromised by a third party. For this reason, Compute Canada is modifying its policies and practices regarding SSH, the principal tool used to provide secure access to its clusters. Some users may have to update their SSH client software, some may have to generate a new public/private key-pair, and everyone will have to update the local copy of the "host key" which is used to identify each Compute Canada cluster.
