In a previous blog post we reported that Google and Microsoft are encouraging Certification Authorities (CAs) to depreciate the vulnerable and outdated SHA-1 cryptographic algorithm and move to the stronger SHA-2.
Starting January 1, 2016, CAs must not issue any new SSL certificates using the SHA-1 hash algorithm. CAs may continue to sign certificates to verify OCSP responses using SHA-1 until January 1, 2017. This year also began with an important update.
