DES和3DES加密算法，C语言，适用于单片机

//DES算法 unsigned char DES_Encrypt(unsigned char *plainBuffer, unsigned char *keyBuffer, unsigned char *cipherBuffer);//加密数据 unsigned char DES_Decrypt(unsigned char *cipherBuffer, unsigned char *keyBuffer, unsigned char *plainBuffer);//解密数据 //3DES算法 unsigned char D3DES_Encrypt(unsigned char *plainBuffer, unsigned char *keyBuffer, unsigned char *cipherBuffer);//加密数据 unsigned char D3DES_Decrypt(unsigned char *cipherBuffer, unsigned char *keyBuffer, unsigned char *plainBuffer);//解密数据
