	fSekrit  License: Freeware
	fSekrit is a small application for keeping encrypted notes. The real advantage of fSekrit is that notes are truly self-contained; the editor program and your note are merged together into a tiny self-contained program file, removing the need to install a special application to view your data. This makes fSekrit ideal for keeping encrypted notes on, for example, USB flash drives. Another advantage of using fSekrit is that your un-encrypted data is never stored on your harddisk. With a traditional encryption utility you would have to decrypt your file to disk, view or edit it, and then re-encrypt it, and unless you use secure file wiping tools, it would be a trivial matter for someone to to retrieve your un-encrypted data, even though you have deleted it. This can't be done with fSekrit, though, since it never stores your un-encrypted data on disk. Author: DonationCoder| Date: 31-01-2006 | Size: 43 KB

	CryptoText  License: Freeware
	CryptoText is a COM encryption component written in ATL3.0 for Windows 9x, NT4.0 and Windows 2000/XP. It provides simple access to the CryptoAPI in Windows from Visual Basic, Visual C++ and scripting languages (eg ASP). As well as being a standalone product CryptoText can be used with CryptoTextCE for the PocketPC / Windows CE platform to exchange encrypted data with handheld devices. CryptoText encrypts the input text data, and converts the resulting binary encrypted form to a series of ASCII characters which are suitable for use in a SQL statement, or for storage in a text/.ini file. For example the text 'My Password' might become the text string '79978e13df1019826c16944fe1'. This type of conversion is necessary because certain characters are reserved and have special meanings in an SQL statement, and by default the Windows CryptoAPI functions will take binary input data (your text) and map each of the characters to a binary number in the range 0 - 255. The simplest solution, although somewhat wasteful of space, is to convert the binary number into a string representation of the equivalent hex number, guaranteeing that only the characters 0-9 and a-f will be present.

	CHAOS Shredder  License: Freeware
	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! When you delete a file from Windows, Windows just mark the file as deleted in file allocation table, but the data of the file is still on your hard disk, there are many tools available which can let others easily recover your sensitive files even after you have formated the hard disk. Sensitive data can easily fall into the wrong hands. And because Windows is not capable of deleting information beyond recovery, you are at risk! Passwords, financial documents, even those "about last night" e-mails are fair game for the IT professionals, computer technicians or hackers. CHAOS Shredder allows you to purge, wipe and erase data with methods that far exceed US Department of Defense standards for file deletion (DOD 5220.22).

	CryptoTextCE  License: Freeware
	CryptoTextCE is an ActiveX / COM component written in ATLCE for the PocketPC. It provides simple access to the CryptoAPI in Windows CE from embedded Visual Basic and embedded Visual C++. CryptoTextCE is a companion product to CryptoText for the desktop, and data encrypted on the PocketPC using CryptoTextCE can be decrypted on Windows NT/9x using CryptoText and vice versa. If you are collecting sensitive data on a PocketPC device and transferring it to a destop PC or server using SQL Server CE or some other form of file based synchronisation, you can use CryptoTextCE to encrypt the data before transfer and CryptoText to decrypt it again on the server. As with CryptoText, CryptoTextCE encrypts the input text data and converts the resulting binary data to a series of characters which are suitable for use in a SQL statement, or for storage in a text/.ini file. The additional step performed by CryptoTextCE is the optional conversion from a UNICODE string to an ANSI string before encryption. This addresses the issue that all strings in eVB for the PocketPC are held as two byte UNICODE characters internally. If you are not making used of the extended character sets available with UNICODE the conversion to ANSI reduces the size of the encrypted data, and increases compatability with desktop Windows operating systems.

	BigSpeed Secure Socket Library  License: Freeware
	BigSpeed Secure Socket Library is an ActiveX control that dramatically simplifies and accelerates the development of proprietary communication solutions over the Internet. It implements a flexible message-oriented protocol on top of a single TCP connection. The transfered data are scrambled using on-the-fly 128-bit AES encryption with random session keys, without need of SSL certificates. The security is provided in two different modes: symmetric encryption with shared secret key and asymmetric encryption with 1024-bit public/private keys. Transport level authentication is available with optional digital fingerprints or secret keys. Building a virtual private application network is just a matter of setting the same crypto key on two or more sites. BigSpeed Secure Socket Library can be used both on client and server side, with centralized management of all connections. Information is exchanged through typed data packets identified by a command code. The library takes care of all low-level tasks: packetizing/depacketizing, compression/decompression, encryption/decryption, sending, receiving, buffer congestion and flow control. There is support for automatic DNS name resolution and SOCKS proxy servers. BigSpeed Secure Socket Library utilizes an elegant event-driven paradigm for easy integration into Windows applications. A special attention is paid to provide responsive user interface while maintaining maximum bandwidth efficiency. Carefully designed set of properties, methods, and events offers great flexibility to develop innovative communication software. Sample applications for chat, alert messaging, and file transfer are included in Visual Basic 6, Visual Basic .NET, Visual C++ .NET, and Delphi 7.
