If you currently store sensitive credentials in plaintext to automate scripting or integration to other systems, you should consider an extra layer of security by storing them encrypted using GPG. There is no fullproof way to hide sensitive information for a service that also needs to decrypt them as part of normal operations (think DVD … Linux: Using GPG encrypted credentials for enhanced security
