3des-des

说明：  一个应用密码学的源代码，主要完成应用密码方面的功能。(a Cryptographic Application source code, application code to complete the function.)

实现维吉尼亚密码，用键盘接收明文和密钥，屏幕打印密文和解密后的明文。 可以实现：大小写敏感，明文小写则密文大写，明文大写则密文小写输出，注意输入的健壮性控制，明文字符超出字符集后保留原文(Virginia to achieve the password, use the keyboard to receive the plaintext and the key, the screen printing ciphertext and the decrypted plaintext. Can be achieved: case sensitive, then the ciphertext plaintext lowercase uppercase, lowercase plaintext ciphertext output is capital, pay attention to the robustness of the control input, plaintext characters out retain the original character set)

Base64 crypt/decrypt

RSA公钥加密，用C实现，大家可以参考一下-RSA public key encryption, using C to achieve, we can refer to

this a vhdl program for crc encoder and decoder-this is a vhdl program for crc encoder and decoder

说明：  一个完整的des演示程序 ，在linux下编译通过(Des a complete demonstration of the procedures adopted in the compiler under linux)

高级加密标准AES优胜算法Rijndael c语言源代码。-Advanced Encryption Standard algorithm Rijndael winning c language source code.

本代码实现了维吉尼亚密码，维吉尼亚密码是基于简单的凯撒密码改进而来的多表替换密码，代码简单，供交流学习使用。
