When you delete a file from Windows it just mark the file as deleted in file allocation table, but the data of the file is still on your hard disk, Windows does not physically remove deleted files from your hard disk. Emptying your Recycle Bin does NOT protect you at all. Your sensitive files can be recovered, even after you format your hard disk! This powerful program helps you shred important files & folders so that they cannot be restored & prevent attempts to recover sensitive deleted files from your hard drive by data recovery or forensic software. Shredder allows you to purge, wipe & erase data with methods that far exceed US Department of Defence standards for file deletion (DOD 5220.22). Easily automate the cleaning process with batch files, shortcuts and scheduler. Completely remove sensitive data from your hard drive by overwriting it several times with carefully selected patterns. Overwrites all bits in selected files, including cluster slack space, with binary 1's, 0's, and/or random bit patterns. Supports complete folder deletions including subfolders. Shreds disk free space so you can even use shredder to destroy previously deleted files on your hard drive. Drag & Drop files or entire folders Delete even if the file is locked! No trails are left of any compromising or confidential information. Easily choose the number of overwrites according to your security ambitions. The higher the number the less the probability that even finest magnetic tracks could be detected. The Department of Defense (DOD 5220.22-M) recommends seven passes for top security. You can also shred files by right-clicking on them from the MS Windows Explorer or on the recycle bin and selecting the shred item on the popup context menu.

CryptoDisk is a powerful tool for creating and managing virtual encrypted disks (encrypted volumes). It creates encrypted volume within a file on a hard drive or any external data storage device (flash memory card, USB drive, etc) and then mount it as a real disk. All the data are automatically encrypted using your password right before they are saved to disk or decrypted right before they are loaded, without any user intervention. Mounted volumes behave as real physical disk drives, however even when the volume is mounted, data stored in the volume is still encrypted.

Why do you need CryptoDisk?

To protect your sensitive information. For example, you can hide your personal information from other people who might have access to your PC, or encrypt your files on a removable storage device for transportation to prevent that the files can be accessed when the device is stolen or lost.

With the onset of the information age, laptops have become an invaluable resource to individuals and companies everywhere. However, laptop theft has been on the rise and as a result many organizations have found themselves victims of potential data breaches that affect their employees and customers, as well as their reputations. A stolen laptop often means loss of sensitive data that is stored on that machine, which is likely to lead to a risk of identity theft.

Depending on what is kept on a particular laptop, without proper security precautions a thief can easily get a hold of such information as personal bookkeeping files, Word documents containing passwords, addresses, as well as employee and customer information stored on a laptop.

Advanced File Calculator is a cryptographic data hash calculation software for files. Simply drag and drop files in this calculator and hash string for the files will be displayed on the fly. Supported cryptographic hash calculation algorithms include CRC32 control sum, GOST hash, MD2, MD4, MD5, SHA-1, HA2 (256), SHA2 (384), SHA2 (512). You may copy separate hash string corresponding to the file contents data or export them in to text file for future use. This software is capable of up to 1000 concurent hash calculations. Webmasters can also benefot from this utility to calculate and place MD5 hash strings values on their website to verify the integrity of the data.

SecureBridge is a library of nonvisual components for Delphi, Delphi for .NET and C++Builder. They provide support for secure connection with remote services in public networks using SSH protocol.

It is enough to place components that implement functionality of the client and storage, and specify the server adress and the user login information to establish secure connection using SecureBridge.

SecureBridge includes the following features:

* Full support for SSH2, SSL 3.0, and TLS 1.0 protocols
* Fast and customizable SSH server, SSH client, and SSL client
* Support for most SSH2-compatible clients and servers including OpenSSH
* Compatible with any application that works through TCP with protocols like SMTP, POP, IMAP, etc.
* Ability to work with system and external certificate storages through CryptoAPI
* Protection against diverse crypto attacks
* Support for symmetric (Blowfish, AES128, Cast128, TripleDES) and asymmetric (RSA, DSA) algorithms
* Support for SHA1 and MD5 hashing algorithms
* Authentication by password or by public key
* Tight integration with Indy and Data Access Components for MySQL
* High performance
* Reliable and convenient maintenance of asymmetric keys
* Facility for storing users, passwords, and public keys for an SSH server
