ava加密擴展即Java Cryptography Extension,簡稱JCE。它是Sun的加密服務軟件,包含了加密和密匙生成功能。JCE是JCA(Java Cryptography Architecture)的一種擴展。 JCE沒有規定具體的加密算法,但提供了一個框架,加密算法的具體實現可以作為服務提供者加入。除了JCE框架之外,JCE軟件包還包含了SunJCE服務提供者,其中包括許多有用的加密算法,比如DES(Data encryption Standard)和Blowfish。 為簡單計,在本文中我們將用DES算法加密和解密字節碼。下面是用JCE加密和解密數據必須遵循的基本步驟: 步驟1:生成一個安全密匙。在加密或解密任何數據之前需要有一個密匙。密匙是隨同被加密的應用一起發布的一小段數據,Listing 3顯示了如何生成一個密匙。 【Listing 3:生成一個密匙】

這是一篇有關混沌在視頻中加密的文章,題目為:A fast video encryption scheme based-on chaos。不過看看懂還是要花一些時間的,不過我可以和大家交流。還有這是英文作寫。

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.

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.
