A system for checking the integrity and authority of information includes a user platform, a communication channel, and a remote platform. The remote platform transmits the information to the user platform via the communication channel. The user platform, which lacks a public key for the information, verifies the authority and integrity of the information by comparing a transformation value of the information generated on the platform to a transformation value supplied by a user. The platform is also capable of authenticating the information by displaying the transformation value generated from the information and requesting that the user match the transformation value generated from the information with a transformation value known to the user.
