In recent years, digital certificates have become one of the most widely accepted public key technologies used to secure electronic communications that are transmitted over the Internet. To promote the use of this technology, the Secure Information Exchange Services group within Information Technology has established the Virginia Tech Certification Authority (VTCA) to provide a digital certificate service to the campus community.
Digital certificates are electronic identity credentials which use encryption to support secure access to a large number of web services and applications on campus.
The VTCA will play an increasingly significant role by providing several important security functions including strong digital identity credentials for authentication; strong encryption for data communications and storage privacy; digital signatures which support non-repudiation of online transactions; and document integrity using digital signatures.
SIES will migrate the VT Global Qualified Server CA SSL certificate chain from SHA-1 to SHA-256 next Wednesday 2/18/2015 at 5:00pm. This change compliments the September, 2014, upgrade for end entity SSL certificates, to ensure that all certificates in the chain are signed using SHA-256.
The latest version of the Chrome browser (40) complains about sites where the SSL certificate is SHA-1. New SHA-256 certificates should be requested through IMS for any SSL certificates using SHA-1 beginning on Thursday, 2/19/2015.
The Secure Information Exchange Services (SIES) group will be migrating the VT Global Qualified Server SSL certificate profile from SHA-1 to SHA-256 on September 19, 2014 at 5:00pm. After the migration is completed, all SSL certificates issued by the VT Global Qualified Server CA will be signed using SHA-256.
