Extract data from database.json to use with Steam Desktop Authenticator

[RalphORama]

I'd like to extract the information required to generate an maFile to use with Steam Desktop Authenticator so I can use the trade confirmations feature. Is there a way to extract the data from "sentry" in database.json to use with Steam Desktop Authenticator's maFile format?

Example maFile:

{"shared_secret":"REPLACEME","serial_number":"REPLACEME","revocation_code":"REPLACEME","uri":"REPLACEME","server_time":REPLACEME,"account_name":"REPLACEME","token_gid":"REPLACEME","identity_secret":"REPLACEME","secret_1":"REPLACEME","status":1,"device_id":"iphone:REPLACEME","fully_enrolled":true,"Session":{"SessionID":"","SteamLogin":"","SteamLoginSecure":"","WebCookie":"","OAuthToken":"","SteamID":REPLACEME}}
