Freeware: Cryptoapi

	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.

	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.
