提供加密的聊天程序。使用对称加密算法…

利用VC来实现一个简单的DES加密程序，他能完成DES算法的全部步骤，不过只能使用64位密码对64位明文进行加密-VC to achieve a simple DES encryption program, he can finish all the DES algorithm steps, but only use 64 to 64 passwords expressly encryption

它也可以用来解除Adobe Acrobat PDF文件密码的工具，它可以帮助解决加密PDF无法编辑和复制/打印的问题，支持所有版本的Acrobat加密(包含7.x)，也支持128位加密。 -It also can be used to lift the Adobe Acrobat PDF files password tool, it can help to solve encrypted PDF can not edit and copy/print the questions, and support all versions of Acrobat encryption (including 7.x), also supports 128-bit encryption.

哈希数据编码解码实现（Hash） 需安全openssl等安全证书-Hash data codec implementation (Hash) need to secure safety certificate openssl, etc.

VHDL implementation of the twofish cipher for 128,192 and 256 bit keys. The implementation is in library-like form All needed components up to, including the round/key schedule circuits are implemented, giving the flexibility to be combined in different architectures (iterative, rolled out/pipelined etc). Manual in English is included with more details about how to use the components and/or how to optimize some of them. All testbenches are provided (tables, variable key/text, ECB/CBC monte carlo) for 128, 192 and 256 bit key sizes, along with their respective vector files.-VHDL implementation of the twofish cipher for 128,192 and 256 bit keys.
