# CI/CD Environment Variables
Environment variables are applied to environments via the runner and can be set from the project's **Settings > CI/CD** page.
2021-02-03 16:09:17 -05:00
The values are encrypted using [`aes-256-cbc` ](https://en.wikipedia.org/wiki/Advanced_Encryption_Standard ) and stored in the database.
2020-03-19 05:09:27 -04:00
This data can only be decrypted with a valid [secrets file ](../raketasks/backup_restore.md#when-the-secrets-file-is-lost ).
