Variable encryption

Environment variables are a great way to store fragile data, such as passwords or API keys, that you would otherwise have to keep hardcoded in your scripts.

Here's how we ensure the security of environment variables:

1. Before saving, every encrypted variable is salted (unique salt) and encrypted
2. The variable value isn't displayed while the action is edited
3. The values of encrypted environment variables are hashed in the logs of the pipeline actions
