ASP.net自带了一个MD5和SHA1加密类库! 下面是调用此类库的两种加密方法:
=====================
public string GetMD5(string strData) { //使用MD5加密方法: System.Security.Cryptography.MD5 md5 = new System.Security.Cryptography.MD5CryptoServiceProvider(); byte[] md5Bytes = System.Text.Encoding.Default.GetBytes(strData); byte[] cryString = md5.ComputeHash(md5Bytes); string md5Str = string.Empty; for (int i=0;i<cryString.Length;i++) { md5Str += cryString[i].ToString("X2"); } return md5Str; }
public string GetEncrypt(string strData,string strType) { //使用MD5或SHA1的加密方法: string strCryData = string.Empty; if (strType.ToUpper() == "SHA1") { strCryData = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(strData,"SHA1"); } else if (strType.ToUpper() == "MD5") { strCryData = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(strData,"MD5"); } return strCryData; }
