Signing secrets in mobile CI pipelines

Signing, migrations, supply-chain integrity and store delivery.

Build and distribution1 min readEditorial methods

Signing keys and publication tokens are high-value pipeline assets. Keep them out of repositories and logs.

Evaluation approach

Use least privilege and prevent untrusted contributions from accessing release secrets. Connect key use to approved publication.

Application example

An external pull request must not execute commands with store-upload credentials.

Limits and considerations

A secret-variable feature does not make every command using it safe.

Can an error disclose a secret?

Failed commands may print different details. Inspect failure paths as well as successful builds, including subprocess and third-party masking behavior.

Checks and decisions

  • Narrow job privileges
  • Inspect logs
  • Protect contribution boundaries
