Ashraf, Glad to hear it fixed it. I have an existing Jira [1] filed which would include strengthening the default sensitive key algorithm, but would also require creating a tool to seamlessly upgrade the encrypted values from the previous algorithm. This tool could also support migrating values encrypted with a different key when it is changed. I’m not sure it will go in 1.0 because of the amount of work remaining, but I will update the ticket with this note.
