用vc++实现des算法，此算法主要实现简单的明文加密、解密-Des algorithm with explicit encryption, decryption! ! !

用verilog实现的DES(Data Encryption Standard数据加密标准)，把64位明文输入变为64位密文输出块。-Using DES (Data Encryption Standard Data Encryption Standard) verilog to achieve, the 64 plaintext input into 64 output ciphertext block.

des数据加密系统，有密钥，有密文，明文！-des data encryption system, there are key, with ciphertext, plaintext!

DES加密算法硬件verilog实现，包含testbench，加密主模块encrypt，明文变换模块LRToCiphertextConverter，NextRi模块等子模块。-DES encrypt verilog
