Managing certificates during a time of key size migration can be difficult. Website or production outages can be costly and have a negative impact to business. This guide aims to help educate and inform users of TLS/SSL certificates about the upcoming change in key lengths and tips on managing their transition to using stronger SSL certificates.

Until the recently, the RSA algorithm, first publically described in 1977 has been the only algorithm available for commercial digital signing certificates. It remains the de facto standard although now commercial certificates based on the DSA and ECC algorithms are now available.
