Migrating certificates during a major key size migration can be difficult at best. I’m going to give you some background, share a great video we have produced, as well as share seven steps to aid in this migration.
Background - Key Sizes Change with Time
Since the RSA algorithm was first publically described in 1977 by Ron Rivest, Adi Shamir, and Len Adleman, 17 key sizes have been factored (hacked). So far the highest key size that was factored was RSA 768-bit in 2009. As cloud computing grows so does the threat that RSA 1024-bit will be factored as well.
Industry Response – Bring 1024-bit Certificate to End-of-Life
In order to be proactive, Certification Authorities (CAs) have been tasked to bring these certificates to end-of-life by the end of 2013. An end date of December 31, 2013 was listed by...
