Industry moves to 3072-bit key minimum RSA code signing certificates

Starting May 27, 2021, to comply with new industry standards for code signing certificates, DigiCert will make the following changes to our code signing certificate process.

  • Stop issuing 2048-bit key code signing certificates
  • Only issue 3072-bit key or stronger code signing certificates
  • Use 4096-bit key intermediate CA and root certificates to issue our code signing certificates.

See Appendix A in the Baseline Requirements for the Issuance and Management of Publicly-Trusted Code Signing Certificates to learn more about these industry changes,

How do these changes affect my existing 2048-bit key certificates?

All existing 2048-bit key size code signing certificates issued before May 27, 2021, will remain active. You can continue to use these certificates to sign code until they expire.

What if I need 2048-bit key code signing certificates?

Take these actions, as needed, before May 27, 2021:

  • Order new 2048-bit key certificates
  • Renew expiring 2048-bit key certificates
  • Reissue 2048-bit key certificates

How do these changes affect my code signing certificate process starting May 27, 2021?

Reissues for code signing certificate

Starting May 27, 2021, all reissued code signing certificates will be:

  • 3072-bit key or stronger. See eTokens for EV code signing certificates and HSMs for EV code signing certificates below.
  • Automatically issued from new intermediate CA and root certificates. See New ICA and root certificates below.

New and renewed code signing certificates

Starting May 27, 2021, all new and renewed code signing certificates will be:

  • 3072-bit key or stronger. See eTokens for EV code signing certificates and HSMs for EV code signing certificates below.
  • Automatically issued from new intermediate CA and root certificates. See New ICA and root certificates below.

CSRs for code signing certificates

Starting May 27, 2021, you must use a 3072-bit RSA key or larger to generate all certificate signing requests (CSR). We will no longer accept 2048-bit key CSRs for code signing certificate requests.

eTokens for EV code signing certificates

Starting May 27, 2021, you must use an eToken that supports 3072-bit keys when you reissue, order, or renew an EV code signing certificate.

  • When you order or renew an EV code signing certificate, DigiCert includes a 3072-bit eToken with your purchase. DigiCert provides an eToken with the Preconfigured Hardware Token provisioning option.
  • When your reissue your EV code signing certificate reissues, you must provide your own 3072-bit eToken. If you don't have one, you will be unable to install your reissued certificate on your eToken.
  • You must have a FIPS 140-2 Level 2 or Common Criteria EAL4+ compliant device.

HSMs for EV code signing certificates

Starting May 27, 2021, you must use an HSM that supports 3072-bit keys. Contact your HSM vendor for more information.

New ICA and root certificates

Starting May 27, 2021, DigiCert will issue all new code signing certificates from our new RSA and ECC intermediate CA and root certificates (new, renewed, and reissued).

RSA ICA and root certificates:

  • DigiCert Trusted G4 Code Signing RSA4096 SHA384 2021 CA1
  • DigiCert Trusted Root G4

ECC ICA and root certificates:

  • DigiCert Global G3 Code Signing ECC SHA384 2021 CA1
  • DigiCert Global Root G3

No action is required unless you practice certificate pinning, hard code certificate acceptance, or operate a trust store.

If you do any of these things, we recommend updating your environment as soon as possible. Stop pinning and hard coding ICAs or make the necessary changes to ensure certificates issued from the new ICA certificates are trusted (in other words, they can chain up to their issuing ICA and trusted root certificates).

DigiCert 停止颁发 SHA-1 代码签名证书

星期二, 2020 年 12 月 1 日 MST,DigiCert 将停止颁发 SHA-1 代码签名证书和 SHA-1 EV 代码签名证书。

注意:所有现有的 SHA-1 代码签名/EV 代码签名证书在到期前将一直有效。

DigiCert 为什么进行这些更改?

为了遵循新的行业标准,证书颁发机构 (CA) 必须在 2021 年 1 月 1 日之前进行以下更改:

  • 停止颁发 SHA-1 代码签名证书
  • 停止使用 SHA-1 中间证书 CA 和 SHA-1 根证书颁发 SHA-256 算法代码签名和时间戳证书

请参阅关于颁发和管理公共信任的代码签名证书的基准要求附录 A

SHA-1 代码签名证书更改对我有什么影响?

如果您依赖于 SHA-1 代码签名证书,请在 2020 年 12 月 1 日之前根据需要执行以下操作:

  • 获取新的 SHA-1 证书
  • 续订 SHA-1 证书
  • 补发和获取必需的 SHA-1 证书

有关 2020 年 12 月 1 日更改的更多信息,请参阅 我们的知识库文章 DigiCert 停止颁发 SHA-1 代码签名证书

如果您有其他疑问,请联系客户经理或我们的 支持团队

EV 代码签名证书补发上的签名哈希选项

我们更新了扩展验证 (EV) 代码签名补发流程。现在,在补发 EV 代码签名证书时,可以为该证书选择签名哈希:SHA-256SHA-1

有关更多信息,请参阅我们的补发 EV 代码签名证书或重新发送密钥说明。
