I'm building a script that needs access to a mailbox, and I want to ensure that the password isn't stored in plain text for security reasons. What are the best practices for encrypting passwords on a Linux server so that my Python or Shell script can access them securely?

For the most secure approach, consider using a password vault. Tools like Pass can store your passwords securely, and you can easily invoke them in your script when needed.
Locally, I keep a configuration file with environment variables for API keys and URLs. When I need a password or key, I just source that config file. You could take it a step further and prompt for it if it's missing, then cache it somewhere.
If I absolutely must include credentials in my script, I create a DPAPI encrypted file using the service account that the script will run under. I store this encrypted file in a location that only that account can access. This method enhances security significantly, though it can get complex if you're using gMSA for even more protection. I could share my scripts if you're interested, although I see your focus is on Linux!
One effective method is to use environment variables for storing your passwords. Alternatively, you can employ secret management services or key vaults for added security, especially if you're dealing with sensitive data like mailboxes. Just keep in mind that environment variables might not be the most secure option due to potential leaks into logs or access by other processes running under the same user context.
It’s important to note that people shouldn’t be downvoting answers based just on the title alone. The OP is looking for secure methods to handle passwords, and that deserves proper input.
I'd love to see your scripts if you can share them!
