Thanks, very interesting article!
I guess there is a small glitch in this line:
var db_access = deserializeJSON(db_access_value);

It should be db_secret_value instead of db_access_value imho?

Good catch!

Thanks for taking the time to point that out. I've corrected it!

Thanks for this example. It was exactly what I was looking for and was easy to implement.

Glad you found it helpful - and thanks for taking the time to comment - much appreciated!
