加密密钥和解密密钥要求一样,用控制台测试如下: string key = "451AEFBD6920AC271"; string sec = "ID=sa;Password=123456;"; string des = sec.EncryptDES(key); string final = des.DecryptDES(key); Console.WriteLine("加密前:"+sec+",加密后:"+des + ",解密后:" + final); Console.ReadLine(...

DES_ENCRYPT(string, [key]) This function returns encrypted text using the triple DES algorithm with a 128-bit key length. It returns NULL if an error occurs. The function is available as of version 4.0.1 of MySQL. This function requires MySQL to be configured for SSL support. In addition...
