SHA-2 and SHA-256 Support

Minimum Supported Version

Content Security Reporter 2.2.0 that is dual signed with SHA-1 and SHA-256 certificates.


SHA-1 is a legacy cryptographic hash that many in the security community believe is no longer secure. Microsoft will eventually deprecate the use of the SHA-1 hashing algorithm for code-signing certificates. We employ code-signing certificates that use the Secure Hash Algorithm (SHA) computed with a 256-bit hash value to digitally sign binaries. These certificates are SHA-256 code-signing certificates and SHA-256 is a member of the SHA-2 family. The SHA-2 family consists of six hash functions with digests (hash values) that are 224, 256, 384, or 512 bits: SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, SHA-512/256. 

Our products are dual-signed with SHA-1 and SHA-256 code-signing certificates. Dual signatures ensure backward compatibility with older operating system versions that don't support SHA-2.
