FlexCompress is a high-speed compression library developed to provide archive functionality for your applications. This solution provides flexible compression and strong Encryption algorithms that allows you to integrate archiving or backup features into your programs in a fast and easy way.
Base64 demonstrates how easy it is to decipher
plaintext usernames and passwords. Never login to a public network resource
unless some type of Encryption is being used, secure socket layer is one example.
Most FTP sites also use plaintext passwords.
PeerSec Networks MatrixSSL?is an embedded SSL implementation designed for small footprint applications and devices. PeerSec Networks offers a fully supported, commercial version as well as an open source version that is available for download. PeerSec MatrixSSL allows secure management of remote devices. Several secure embedded Web servers also use MatrixSSL for their Encryption layer.

What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple Encryption technique is used(In VB - The same technique can be implemented in "c" also.) Program flow Explained * Open the File to be encrypted for Binary Access Read(Say Source File) * Open a temparory file where encrypted data is stored for Binary Access Write(Say Destination File) * Loop through the Source File Byte by Byte * For each byte read from the file, Complement the data. (Using Not operator (in C we have to use "~" operator) * Write Complemented Data to Destination File * Delete the Source File * Rename Destination file as Source File(Now Encryption is over)
The Microsoft® Cryptographic Application Programming Interface (CryptoAPI) provides services that enable application developers to add authentication, encoding, and Encryption to their Microsoft Win32® -based applications. Application developers can use the functions in the CryptoAPI without knowing anything about the underlying implementation, in much the same way as they can use a graphics library without knowing anything about the particular graphics hardware configuration.
This library allows creating, modifying and extracting zip archives in the compatible way with PKZIP (2.5 and higher) and WinZip. Supported are all possible operations on the zip archive: creating, extracting, adding, deleting files from the archive, modifications of the existing archive. There is also the support for creating and extracting multiple disk archives (on non-removable devices as well) and for password Encryption and decryption. This module uses compression and decompression functions from zlib library by Jean-loup Gailly and Mark Adler.
