R-Crypto is an easy-to-use system utility that protects your confidential information and personal data on a desktop, notebook, or a removable data storage device against unauthorized access.
R-Crypto protects the data by creating encrypted on-the-fly virtual disks (virtual data storage devices). That means that the data is being automatically encrypted just before it is being written to the disk and is being automatically decrypted right after it is being read from the disk without user intervention. That is the data is being encrypted and decrypted in real time and fully transparently to the user. All data (such as file and folder names, and content of all files) stored on such disks is constantly encrypted. The access to data on the virtual encrypted disk is impossible unless the user provides a correct password. At the same time, all operations for connected virtual encrypted disks do not differ from those for conventional ones.
All data of the encrypted virtual disk is stored together with disk metadata in a file-container. That means that such disk is actually an ordinary file that can be stored on any data storage device, be it a hard drive, USB-disk, CD, DVD, or a network resource.
R-Crypto encrypts data on virtual disks using the cryptographic infrastructure of the Microsoft Windows operating system. This infrastructure allows the users to use various installable cryptographic service providers, including those that are already pre-installed. For example, Microsoft AES Cryptographic Provider is one of the pre-installed cryptographic service providers in Windows XP and Vista that implements the modern and most secure encryption algorithm Advanced Encryption Standard (AES) with key length of 128, 192, and 256 bits.
Such approach allows the users to select themselves the cryptographic sub-system that satisfies their requirements. It also reduces limitations on the use of R-Crypto in organizations that require certification for such products to meet certain governmental or corporate standards.
