For instance, on Windows Server 2003 without MS13-095 or Windows XP SP2 Chrome will not connect to pages using SHA-2 certs. ** Chrome is capable of supporting SHA-2 certificates as of version 1.0, however through version 37 it is dependent on the operating system. 1.6 improved this issue for some users, with the issue being resolved as of version 2.2.

In practice, some users may encounter issues with validating certificates that use cross certificates (these help chain certificates to alternate roots). * Android has the technical capability of handling SHA-256 certificates right from version 1.0. To purchase a trusted SHA-256 certificate, contact a GlobalSign representative.Īctive Directory Federation Server (AD FS) Read our Hash Functions article for a better understanding of how they work and how they are used to validate certificates and documents.įor GlobalSign’s policy on SHA-256 issuance as well as important dates set by Microsoft, Google, and Mozilla, please read the SHA-256 Rollout article.

As a general rule, SHA-256 is supported on OS X 10.5+ and Windows XP SP3+. This article focuses specifically on SHA-256 and its compatibility with various software platforms and operating systems. Not all software supports every digest size within the SHA-2 family. The 256 in SHA-256 represents the bit size of the hash output or digest when the hash function is performed. SHA-2 is a set of cryptographic hash functions which includes SHA-224, SHA-256, and SHA-512.
