求教一个关于.net加密算法的问题。SHA512
网上看到的跟自己写的机密方式都用过了。为什么加密出来的结果不一样？
//方法一：
public static string GETSHA512Encrypt(string strDigestStr)
{
byte[] aryEncodedData;
SHA512Managed inDigest = new SHA512Managed();
UTF8Encoding inUTF8 = new UTF8Encoding();
aryEncodedData = inUTF8.GetBytes(strDigestStr);
aryEncodedData = inDigest.ComputeHash(aryEncodedData);
String tmp = "";
for (int nLoop = 0; nLoop < aryEncodedData.Length; nLoop++)
tmp += aryEncodedData[nLoop].ToString("X2");
return tmp;
}
//方法二：
public static string SHA512Encrypt(string str)
{
System.Security.Cryptography.SHA512 s512 = new System.Security.Cryptography.SHA512Managed();
byte[] byte1;
byte1 = s512.ComputeHash(Encoding.Default.GetBytes(str));
s512.Clear();
return Convert.ToBase64String(byte1);
}
//方法三： 就在一上面 把 tmp += aryEncodedData[nLoop].ToString("X2"); 改成
tmp += aryEncodedData[nLoop].ToString("");
12 C# 加密算法
[解决办法]
public static string GetSHA512Password(string password)
{
byte[] bytes = Encoding.UTF7.GetBytes(password);
byte[] result;
SHA512 shaM = new SHA512Managed();
result = shaM.ComputeHash(bytes);
StringBuilder sb = new StringBuilder();
foreach (byte num in result)
{
sb.AppendFormat("{0:x2}", num);
}
return sb.ToString();
}
