Google’s new policy to show warnings in the Chrome browser for SHA-1 certificates as early as this November makes migration to SHA-2 a high priority for website operators
LEHI, UT (Sept. 17, 2014) —DigiCert, Inc., a leading global Certificate Authority and provider of trusted identity and authentication services, today released a free tool which helps system administrators analyze their use of SHA-1 hashing algorithms across all domains and subdomains—and map out a path for SHA-2 migration. Google’s Aug. 19 announcement that it would accelerate deprecation of SHA-1 certificates, including giving untrusted warnings to sites with SHA-1 certificates that expire in 2016, makes it necessary for many administrators to migrate to SHA-2 by as early as November or risk their customers receiving downgraded trust indicators in Chrome.
Using the DigiCert® SHA-1 Sunset Tool, administrators can determine validity periods for their SHA-1 SSL certificates and receive information about how Google’s new policy will affect user interaction with these certificates. DigiCert issues new certificates with SHA-2 by default and has done so for nearly a year. For those choosing to migrate their existing SHA-1 to a new DigiCert-issued SHA-2 certificate, DigiCert will provide a free replacement matching the length of the existing certificate licensing term, regardless of whether or not they are a DigiCert customer.
“With the busy holiday shopping season nearing and the threat of a downgraded user trust experience looming for Chrome users, DigiCert is taking extra steps to help ease the burden of accelerated SHA-2 migration timelines for administrators,” said DigiCert CEO Nicholas Hales. “Our new SHA-1 Sunset Tool saves time and effort by providing a comprehensive analysis of an organization’s certificate landscape, including where SHA-1 certificates exist, which software and hardware support SHA-2, and a review of how Google’s new timelines may affect any given site. We also understand that SHA-2 migration involves costly system and device upgrades for organizations and so we’re offering to match for free the remaining term of any existing SHA-1 certificate that is converted to SHA-2.”
Some key timelines are important to keep in mind regarding Google’s SHA-1 deprecation:
- November 2014 – SHA-1 SSL Certificates expiring any time in 2017 will show a warning in Chrome.
- December 2014 – SHA-1 SSL Certificates expiring after June 1, 2016 will show a warning in Chrome.
- Q1 2015 – SHA-1 SSL Certificates expiring any time in 2016 will show a warning in Chrome.
Updated: Additionally, Microsoft has announced the following SHA-1 deprecation timelines:
- January 1, 2016 – Certificate Authorities must stop issuing new SHA-1 SSL Certificates.
- January 1, 2017 – Microsoft will stop trusting SHA-1 SSL Certificates.
Code Signing Certificates
- January 1, 2016 – *For Windows 7 and later, and Windows Server 2008 R2 and later
- Microsoft will stop trusting SHA-1 Code Signing Certificates issued after December 31, 2015 with or without time stamps.
- Microsoft will stop trusting SHA-1 Code Signing Certificates issued before January 1, 2016 without time stamps.
- January 14, 2020 – *For Windows 7 and later, and Windows Server 2008 R2 and later
- Microsoft will stop trusting SHA-1 Code Signing Certificates issued before January 1, 2016 with time stamps.
- January 14, 2020 – *For Windows Vista/Windows 2008
- Microsoft will end support for Windows Vista and Windows 2008. CAs may continue to issue SHA-1 Code Signing Certificates so that developers can continue to support these operating systems until extended support ends.
*Note: For details concerning Microsoft’s support for SHA-1 Code Signing Certificates, please refer to the Windows PKI blog posting SHA1 Deprecation Policy.
In addition to receiving a full report of their current SHA-1 deployment across all domains via the SHA-1 Sunset Tool, administrators can take advantage of other DigiCert tools and features to optimize their certificate deployment. DigiCert customers can use a built-in feature to their customer accounts to monitor SHA-2 migrations as they take place, in real-time, using the SHA-1 Sunset Tool. They also can use their account to issue new certificates and benefit from free reissues at any time. Non-DigiCert customers can access the DigiCert Certificate Inspector to review real-time SSL certificate and endpoint deployment across internal and external networks and identify areas for improvement, including flagging SHA-1 certificates and expiration dates.
