Main features of File Cryprite

File Cryprite (Fcr) is a file/folder encryption programme, designed to provide easy, very fast and very strong encryption of selected files or folders of files for the purposes of

  1. confidential data storage;
  2. semi-transparent "on-the-fly" access to the encrypted files (opening of encrypted files without preliminary manual decryption and without manual encryption after their closing/saving);
  3. one-click desktop en/decryption of any specified lists of separate files and folders;
  4. secure transport of files from computer to computer by any means.

There are essential distinctions between Fcr and other file encryption products. The most important are as follows:

  1. Fcr works basically in a secret key technology, which is much more secure in general than public key solutions, and easier to understand and use.
  2. Compared to other file encryption products which also use secret (symmetric key) technology, Fcr's solutions are much more developed - Fcr provides a complete set, including a hierarchy, of secret keys for different purposes, strong but flexible administration facilities, multi-user operations, different types of passwords, and so on.
  3. Fcr is designed, first and foremost, to encrypt/decrypt your data files, without using or leaving any plain or temporary copies, without disk fragmentation (-unlike other products-) - and encrypting as many files, or folders full of files, and sub-folders, as you wish, fast and easily. Using Fcr interface, you can spend 5 seconds on encrypting operations, which may require 1 minute with most other products, or might even be impossible to do with other products.
  4. The internal encryption engine of Fcr is much faster and much stronger (it's unbreakable!) than other known encryption engines.
  5. The separate utility of Fcr - wpTempD.exe - physically erases/wipes all data left in currently unused (by your choice)
    • Recycle bin,
    • System temp folder,
    • Standard temporary files,
    • Temporary Internet files,
    • Cookies,
    • Internet history,
    • User-defined folders and files/masks (!),
    • residual/temporary data in used files (!),
    • unused clusters (including swap file(!)
    The last two locations can be never seen by your eyes, and can keep for months and years(!) some parts of your significant information, such as bank accounts, the amounts of money, some piquant letters or pictures which may cost you your positive reputation, - and you never mind that some half-educated boy easily get it during playing "tetris"! At least once you absolutely need to completely clean your PC with wpTempD!
    You can read more about wpTempD on "Main features of Disk Cryprite" page.

Looking one step forward, the current version of Fcr already includes the basic features of our current major development projects (into which Fcr will evolve) - Network Cryprite Conductor and Cryprite Exchange Center (CEC). These are designed to provide Internet solutions for the transfer/exchange of encrypted files and folders, for their remote storage in encrypted form and for shared access to remote encrypted files and folders of files - "crypto-shared-rooms" (- systems which might be seen as containing elements of today's VPNs, secure e-mail, direct encrypted file transfer, remote backup systems and secret conference systems). Fcr already provides semi-transparent secret key data storage and exchange of encrypted files in LANs.

The main features of Fcr are:

  • Easy to use and manage, with speedy dialog interfaces;
  • Fcr is a "program-chameleon" which can change its appearance from "Fcr for Professionals" with a hundred features to "Fcr for Idiots" with only 2 buttons to use! It is distributed in a form close to the "Idiots" extreme, and it's capacities can easily be tuned via the Customize menu. Thus, we can say that Fcr CAN BE EXTREMELY EASY to operate;
  • Using our SVC encryption algorithms, Fcr is extremely fast. It encrypts/decrypts files and folders at almost the same speed as one would normally COPY them unencrypted. ("Fcr file" is only 1-20% slower than the "Copy file" operation in Windows or 25-45% in DOS depending on the crypto-algorithm used, processor/disk speed and the amount of RAM);
  • Fcr can encrypt ANY file you want. Nevertheless, there are some files you should normally never want to encrypt: these are the system files (for example command.com) which, if encrypted, would disable your PC. Fcr prevents the user from accidentally encrypting these system files, by providing an "ignore for encryption" list where the user (or an administrator) can mark files, file masks and folders which should never be encrypted;
  • In any case, all encrypted files can easily be restored via the on-board DOS file fcr.exe, which never encrypts itself;
  • Fcr encrypts any number and size of files/folders - reliably, speedily, without deterioration of general programme / system performance. The efficiency of performance of the on-the-fly access to encrypted files (opening files) does not depend on how much encrypted data you have;
  • Fcr's encryption adds not more than 34 bytes to file sizes - and (optionally) can encrypt without requiring any extra space at all - i.e. adding nothing to file sizes! Fcr encrypts data at its existing physical location on a disk, so it leaves no un-encrypted traces (temporary copies) of the data which has been additionally encrypted or wiped;
  • Fcr is not dependent on any single operating system and its possible unreliability problems: Data encrypted in Windows can be opened / decrypted in Dos and vice versa. Fcr has both Windows and Dos (command line) interfaces;
  • Even if the operating system fails, encrypted data is never lost and is easily recoverable;
  • Fcr encrypts files wherever you can see and normally edit them - on a remote (mapped as a local) disk, diskette, ZIP, etc;
  • Fcr has a three level hierarchical password system, with strong SuperUser (Administrator) features which provide a multitude of control options;
  • Fcr operates with static (changeable only by the SuperUser) secret keys (passwords) as well as with optional one-time/session secret keys (passwords), which can be different for different encryptions. It supports different "users", on the same PC, with different fixed passwords (of course, they can be changed, but normally user's passwords stay costant during some time - maybe for some months). Different "users" and their different passwords are normally used for the secure data exchange. All passwords / users freedoms and capacities are under the strong control of the SuperUser;
  • Data and password recovery and observation of local government rules are provided by the SuperUser;
  • Passwords can have any arbitrary length from 0 to 512 bytes - and this length may be restricted by the SuperUser;
  • Fcr can generate unique passwords (in files) and take passwords from files - which may be stored on diskettes, CDs etc.;
  • Fcr provides mobility in encryption - the small (110 Kb) Fcr.exe programme (or even the "lighter" 15kb version of Fcr - Fc1.exe) may be taken with you on diskette for use on any other PC; or may be emailed to your mail correspondent if he doesn't already have complete version of F-Cryprite;
  • Fcr supports encrypted archives, and self decrypting / self extracting archives (DSFX, or SDA), especially convenient for your correspondents who have not Fcr;
  • Supports a special SecretList feature - you list files/ folders anywhere on the disk(s), and, with "one click" decrypt/encrypt these together as a special group. For example all files/folders dealing with a special project - piece of litigation, new patent, etc.;
  • SecretLists, placed to desktop, are very convenient for one-click encrypting / decrypting your important folders and databases, such as "My documents", Address book, the database of all incoming and outgoing e-mail correspondence, etc.
  • Fcr is integrated with MyComputer and Explorer - you can encrypt/decrypt from within these windows or by trailing icons to the Fcr window (which also shows whether a particular file is already encrypted, before it is opened);
  • While working in a LAN or Internet, a currently encrypted file can not be attacked - i.e. cannot be read, stolen, infected by a virus, "reformed" / corrected or damaged so that you will not detect this before you try to use it. Encrypted files are also protected against accidental erasing or damaging.

A recent important development in File Cryprite is a special "Two windows Re-encrypting technology" (patent-pending) for transferring a file securely from one encryption environment (password, user, computer) to another (accessible) environment, by simply trailing the icon to the second window. Operating in a LAN, this permits convenient storage of confidential data on remote PCs, and encrypted data exchange between different users (two or more) sharing some common password, with end-to-end encryption, while permitting the different users to keep their own passwords confidential.

The current Fcr development includes some PKI elements and Cryprite Exchange (Internet) Center (CEC) which integrates 5 base purposes:

  1. Crypto-exchange via the Internet files of any size;
  2. Crypto-exchange via the Internet by messages (similar to e-mail);
  3. Remote crypto-storage of private data;
  4. Remote crypto-shared-rooms;
  5. Desktop and LAN encryption.

CEC intersects with existing VPN, Firewalls and secret mail system systems, but CEC is much easier, cheaper, integrated and powerful.
