# CI/CD Environment Variables[](#cicd-environment-variables "Permalink")
环境变量通过运行程序应用于环境，可以从项目的**"设置">" CI / CD"**页面进行**设置** .
这些值使用[aes-256-cbc](https://en.wikipedia.org/wiki/Advanced_Encryption_Standard)加密并存储在数据库中.
只能使用有效的[机密文件](../raketasks/backup_restore.html#when-the-secrets-file-is-lost)解密此数据.
