DigiCert to stop issuing SHA-1 code signing certificates

On Tuesday, December 1, 2020 MST, DigiCert will stop issuing SHA-1 code signing and SHA-1 EV code signing certificates.

Note: All existing SHA-1 code signing/EV code signing certificates will remain active until they expire.

Why is DigiCert making these changes?

To comply with the new industry standards, certificate authorities (CAs) must make the following changes by January 1, 2021:

  • Stop issuing SHA-1 code signing certificates
  • Stop using SHA-1 intermediate CA and SHA-1 root certificates to issue SHA-256 algorithm code signing and timestamping certificates

See Appendix A in the Baseline Requirements for the Issuance and Management of Publicly-Trusted Code Signing Certificates.

How do the SHA-1 code signing certificate changes affect me?

If you rely on SHA-1 code signing certificates, take these actions as needed before December 1, 2020:

  • Get your new SHA-1 certificates
  • Renew your SHA-1 certificates
  • Reissue and get needed SHA-1 certificates

For more information about the December 1, 2020 changes, see our knowledgebase article DigiCert to Stop Issuing SHA-1 Code Signing Certificates.

DigiCert will stop issuing 2-year public SSL/TLS certificates

On August 27, 2020 5:59 pm MDT (23:59 UTC), DigiCert will stop issuing 2-year public SSL/TLS certificates to prepare for the industry changes to the maximum allowed validity for public SSL/TLS certificates.

After the August 27 deadline, you can only purchase 1-year public SSL/TLS certificates.

What do I need to do?

To ensure you get needed 2-year public SSL/TLS certificates before the August 27 deadline:

  • Take inventory of needed 2-year certificates—new and renewals.
  • Order any 2-year certificates that you need before August 13.
  • Respond to any domain and organization validation requests in a timely manner.

To learn how this change will affect pending certificate orders, reissues, and duplicates, see End of 2-Year DV, OV, and EV public SSL/TLS certificates.

DigiCert Services API

For those using the DigiCert Services API, you'll need to update your API workflows to account for the new maximum certificate validity of 397 days for requests placed after the August 27 deadline. See Services API.

After August 27, 2020

After August 27, you can only purchase 1-year public SSL/TLS certificates. However, to maximize your SSL/TLS coverage, purchase your new certificates with a DigiCert® Multi-year Plan. See Multi-year Plans.

Why is DigiCert making this change?

On September 1, 2020, the industry says good-bye to 2-year certificates. Going forward Certificate Authorities (CA) can only issue public DV, OV, and EV SSL/TLS certificates with a maximum validity of 398 days (approximately 13 months).

DigiCert will implement a 397-day maximum validity for all public SSL/TLS certificates as a safeguard to account for time zone differences and to avoid issuing a public SSL/TLS certificate that exceeds the new 398-day maximum validity requirement.
