CERTIFICATE ACTION REQUIRED | Discontinued use of SHA1 Intermediate CAs used for signing SHA-256 Code Signing certificates

CRITICAL

Description

Per updated Microsoft guidelines, Symantec is discontinuing the use of SHA-1 Intermediate CA Certificates used for signing SHA-256 Code Signing certificates.

Symantec has phased out the use of the VeriSign Class 3 Code Signing 2010 CA, a SHA-1 Intermediate CA certificate, for issuance of SHA-256 Code Signing certificates. This change and the timing are in line with industry best practices.

This was done as Microsoft is now deprecating the use of SHA-256 code signing certificates chained to SHA-1 Intermediate CA certificates; therefore, your code may no longer be trusted on Windows machines. With this change, the SHA-256 end-entity certificates must be chained to SHA-2 intermediate certificates. 

As technology evolves, it is critical to stay ahead of those who wish to defeat cryptographic technologies for their malicious benefit. Symantec is helping to make the Internet more secure by proactively enabling, promoting, and elevating strong cryptographic standards within SSL/TLS and code-signing certificates. As part of this effort, Symantec has made available replacement certificates at no additional charge to our customers.

If your SHA-256 Code Signing certificate is signed by the SHA1 Intermediate CA “VeriSign Class 3 Code Signing 2010 CA”, please obtain a free replacement certificate and re-sign your code with the new certificate.
 

For reference purposes, the details of the SHA-1 Intermediate CA Certificate are listed below.
