CryptoExpert 2008 Professional 7.6.2 

CryptoExpert uses a real-time on-the-fly encryption system to encrypt and decrypt data. Your files are stored in the encrypted form on virtual hard drive with password authentication, but when it is requested by any application, it gets decrypted on-the-fly. Conversely, unencrypted data to be stored is encrypted instantaneously and then stored. The system mounts a volume file to create a "virtual drive" that appears to applications and users like any other physical drive. Any data that the user attempts to write to this drive is intercepted by CryptoExpert, encrypted, and written to the volume file. Attempts to read from this volume are also intercepted, and the relevant data is read by CryptoExpert from the volume file, decrypted, and presented to the application trying to read the data.
