The Vacman Controller allows the verification of passwords and signatures generated by a DIGIPASS. To verify these passwords, the Vacman Controller needs access to the parameters and secrets that were programmed in the DIGIPASS. The Vacman Controller will store this information in what is called the DIGIPASS Blob. The DIGIPASS Blob is a flat data structure that must be stored in the Application Database on the Host computer that runs the Vacman Controller. To prevent fraud from people having access to the database, the DIGIPASS Blob is protected (privacy and integrity) with a 3DES-based encryption.
