I am wondering if there is any encryption I can do to certain column data before its posted to ODK Tables.
I have been trying to use a simple technique through:
- Using simple .replace() function of javascript. So once the data clerk has entered the data I am recoding it using the .replace function e.g a 1 can be assigned to be #. I will then use the assign and calculate to replace the actual value with the replacement. So ODK Table will store this last value. However my challenge is when the data clerk once to review the entered data. I need a way to do reverse replacement. I have been trying to show the actual value in a note but I noted that the display.prompt.text column seem not to be taking the JS formula for replace. I have been trying The key entered is {{data.variable_name}}.replace(‘*’,‘1’) but its failing.
I would appreciate any suggestions on any proven methods.
