If certain local files are manipulated in a certain manner, the validation to use the cryptographic keys can be circumvented. 

"If port encryption is not enabled on the Domino Server, HCL Nomad on Android and iOS Platforms will communicate in clear text and does not currently have a user interface option to change the setting to request an encrypted communication channel with the Domino server.
