des加密算法,用于IP通讯方面的,用VHDL写成的源程序-des encryption algorithm used for IP communications.the source codes are written in VHDL

While there are many AES cores around, this one is designed with LUT6 based FPGA architecture in mind from day one.  The AES Decryption Core for FPGA implements the decryption portion of the AES (a.k.a. Rijndael) algorithm described in the FIPS-197 specification. Key lengths of 128 / 192 / 256 bits are supported, each with a separate instantiation wrapper. Since the core is designed to take advantage of LUT6 based FPGA archit

用JAVA做的模拟电梯的程序,是自己做的- Simulation elevator procedure does which with JAVA, is oneself does

一个用各种加密算法给文件加密的Delphi例子。为了减小文件size把执行文件去掉了。D7下编译。-A full example that encript a file with many motheds.You should sompile it under D7.

该程序是使用恺撒密码和transposotion密码。也许这个计划太简单了，但总比没有强。：V
