HTTPS Security Certificate Change from SHA-1 to SHA-256 Hash Algorithm

Products Affected

All Melissa Data Cloud Services

Effective Date: September 21st, 2015

In keeping with the best and latest security practices of the technology industry, we are updating our HTTPS certificate. Currently, our certificates are signed with the SHA-1 algorithm while the new certificates will be signed with the SHA-256 algorithm. Many leading technology companies are making this change as well. Microsoft and Google have announced deprecation of SHA-1 in 2016.

To ensure uninterrupted access, please make sure your Operating Systems and client applications that use Melissa Data web services are capable of accepting HTTPS certificates with SHA-256. SHA-256 was first published in 2001 so most modern systems should have no trouble with the new certificate.
