Use of the SHA-2 cryptographic signature algorithm has received a significant boost in the wake of the Heartbleed Bug. More than half a million SSL certificates were potentially compromised as a result of the Heartbleed vulnerability — affected certificates require urgent re-issuance and revocation. The good news is that many of the new certificates have been […]
The National Institute of Standards and Technology (NIST) is still using SSL certificates signed with the SHA-1 signature algorithm, despite issuing a Special Publication disallowing the use of this algorithm for digital signature generation after 2013. “SHA-1 shall not be used for digital signature generation after December 31, 2013.” — NIST recommendation The SSL […]
