visual studio - SHA1Managed UWP (C#)

本文关键字：UWP SHA1Managed studio visual | 更新日期: 2023-09-27 18:02:02

我正在为UWP编写应用程序

我有代码

 private string Hash(string input)
 {
     using (SHA1Managed sha1 = new SHA1Managed())
     {
         var hash = sha1.ComputeHash(Encoding.UTF8.GetBytes(input));
         var sb = new StringBuilder(hash.Length * 2);
         foreach (byte b in hash)
         {
             // can be "x2" if you want lowercase
             sb.Append(b.ToString("X2"));
         }
         return sb.ToString();
     }
}

但是它不工作并且显示这个错误

项目文件行抑制状态找不到类型或命名空间名称"SHA1Managed"(您是否缺少using指令或程序集引用?)米兰C:'Users'nemes'Documents'GitHub'Milano_pizza'米兰' woocommerceapiclients .cs 25 Active

我该如何解决这个问题?

visual studio - SHA1Managed UWP (C#)

对于UWP使用HashAlgorithmProvider 

    public string Hash(string input)
    {
        IBuffer buffer = CryptographicBuffer.ConvertStringToBinary(input, BinaryStringEncoding.Utf8);
        HashAlgorithmProvider hashAlgorithm = HashAlgorithmProvider.OpenAlgorithm(HashAlgorithmNames.Sha1);
        var hashByte = hashAlgorithm.HashData(buffer).ToArray();
        var sb = new StringBuilder(hashByte.Length * 2);
        foreach (byte b in hashByte)
        {
            sb.Append(b.ToString("x2"));
        }
        return sb.ToString();
    }

记得加上

using Windows.Security.Cryptography;
using Windows.Security.Cryptography.Core;

SHA1Managed仅适用于Android和iOs，适用于Windows UWP:

如果你想要一个字节数组:

    public byte[] getSHA1MessageDigest(string originalKey)
    {
        IBuffer buffer = CryptographicBuffer.ConvertStringToBinary(originalKey, BinaryStringEncoding.Utf8);
        HashAlgorithmProvider hashAlgorithm = HashAlgorithmProvider.OpenAlgorithm(HashAlgorithmNames.Sha1);
        IBuffer sha1 = hashAlgorithm.HashData(buffer);
        byte[] newByteArray;
        CryptographicBuffer.CopyToByteArray(sha1, out newByteArray);
        return newByteArray;
    }

如果你想要一个字符串作为结果:

    public string getSHA1MessageDigest(string originalKey)
    {
        IBuffer buffer = CryptographicBuffer.ConvertStringToBinary(originalKey, BinaryStringEncoding.Utf8);
        HashAlgorithmProvider hashAlgorithm = HashAlgorithmProvider.OpenAlgorithm(HashAlgorithmNames.Sha1);
        IBuffer sha1 = hashAlgorithm.HashData(buffer);
        byte[] newByteArray;
        CryptographicBuffer.CopyToByteArray(sha1, out newByteArray);
        var sb = new StringBuilder(newByteArray.Length * 2);
        foreach (byte b in newByteArray)
        {
            sb.Append(b.ToString("x2"));
        }
        return sb.ToString();
    }
