About commit signature verification

Using GPG or S/MIME, you can sign tags and commits locally. These tags or commits are marked as verified on GitHub Enterprise Server so other people can be confident that the changes come from a trusted source.

About commit signature verification

You can sign commits and tags locally, to give other people confidence about the origin of a change you have made. If a commit or tag has a GPG or S/MIME signature that is cryptographically verifiable, GitHub Enterprise Server marks the commit or tag "Verified."

Verified commit

If a commit or tag has a signature that can't be verified, GitHub Enterprise Server marks the commit or tag "Unverified."

Repository administrators can enforce required commit signing on a branch to block all commits that are not signed and verified. For more information, see "About protected branches."

Você pode conferir o status de verificação de seus commits ou tags assinados no GitHub Enterprise Server e ver por que as assinaturas de commit podem não ter sido verificadas. Para obter mais informações, confira "Como verificar o status do commit e da verificação de assinatura da tag".

GPG commit signature verification

You can use GPG to sign commits with a GPG key that you generate yourself.

GitHub Enterprise Server uses OpenPGP libraries to confirm that your locally signed commits and tags are cryptographically verifiable against a public key you have added to your account on your GitHub Enterprise Server instance.

To sign commits using GPG and have those commits verified on GitHub Enterprise Server, follow these steps:

  1. Check for existing GPG keys
  2. Generate a new GPG key
  3. Add a GPG key to your GitHub account
  4. Tell Git about your signing key
  5. Sign commits
  6. Sign tags

S/MIME commit signature verification

You can use S/MIME to sign commits with an X.509 key issued by your organization.

GitHub Enterprise Server uses the Debian ca-certificates package, the same trust store used by Mozilla browsers, to confirm that your locally signed commits and tags are cryptographically verifiable against a public key in a trusted root certificate.

Observação: a verificação de assinatura S/MIME está disponível no Git 2.19 ou posterior. Para atualizar sua versão do Git, acesse o site do Git.

To sign commits using S/MIME and have those commits verified on GitHub Enterprise Server, follow these steps:

  1. Tell Git about your signing key
  2. Sign commits
  3. Sign tags

You don't need to upload your public key to GitHub Enterprise Server.
