Thanks for the feedback, Mark - but I wasn't looking for an external solution :-)
What I mainly wanted to know was how the mobile standalone apps cope with the 'cipherNames' property and 'encrypt' command as "industrial strength encryption" is missing. I don't have mobile deployment options so I can't check this for myself.

Monte has an external for doing AES encryption. It works on iOS for the moment.
