C#SHA-2(512)Base64编码哈希

Question

寻找一种方法在C#中从字符串中执行以下操作.

public static String sha512Hex(byte [] data)

计算SHA-512摘要并将值作为十六进制字符串返回.

参数:data - 要摘要的数据返回:SHA-512摘要为十六进制字符串

    private static string GetSHA512(string text)
    {
        UnicodeEncoding UE = new UnicodeEncoding();
        byte[] hashValue;
        byte[] message = UE.GetBytes(text);
        SHA512Managed hashString = new SHA512Managed();
        string encodedData = Convert.ToBase64String(message);
        string hex = "";
        hashValue = hashString.ComputeHash(UE.GetBytes(encodedData));
        foreach (byte x in hashValue)
        {
            hex += String.Format("{0:x2}", x);
        }
        return hex;
    }

Answer 1

将System.Security.Cryptography.SHA512是你需要什么？

var alg = SHA512.Create();
alg.ComputeHash(Encoding.UTF8.GetBytes("test"));
BitConverter.ToString(alg.Hash).Dump();

在LINQPad中执行产生:

EE-26-B0-DD-4A-F7-E7-49-AA-1A-8E-E3-C1-0A-E9-92-3F-61-89-80-77-2E-47-3F-88- 19-A5-D4-94-0E-0D-B2-7A-C1-85-F8-A0-E1-D5-F8-4F-88-BC-88-7F-D6-7B-14-37-32- C3-04-CC-5F-A9-AD-8E-6F-57-F5-00-28-A8-FF

要从您的问题创建方法:

public static string sha512Hex(byte[] data)
{
    using (var alg = SHA512.Create())
    {
        alg.ComputeHash(data);
        return BitConverter.ToString(alg.Hash);
    }
}

Answer 2

有这个工作.从这里采取并修改了一下.

    public static string CreateSHAHash(string Phrase)
    {
        SHA512Managed HashTool = new SHA512Managed();
        Byte[] PhraseAsByte = System.Text.Encoding.UTF8.GetBytes(string.Concat(Phrase));
        Byte[] EncryptedBytes = HashTool.ComputeHash(PhraseAsByte);
        HashTool.Clear();
        return Convert.ToBase64String(EncryptedBytes);
    }
