From the developer:
SecretBox can be used to store all sorts of information: Credit Card details, SSN numbers, Software Licenses, e-mail account details and website passwords. All are easily stored in SecretBox's flexible database.
SecretBox uses the industry standard 256-bit AES encryption to protect your data, but that is just the start. SecretBox takes extra care to never decrypt your information unless absolutely necessary.
