问题描述

我今天在 WinRT 中创建了一个简单的单向 SHA-256 哈希，发现它不起作用.我做了一个验证，显然得到了这个:

I went to create a simple one-way SHA-256 hash in WinRT today and realized it didn't work. I did a validation and apparently got this:

◦API System.Security.Cryptography.SHA256在 MSCORLIB 中管理，此应用程序不支持 PUBLICKEYTOKEN=B77A5C561934E089类型.CryptoWinRT.exe 调用此 API.◦APIMSCORLIB 中的 System.Security.Cryptography.HashAlgorithm，此应用程序不支持 PUBLICKEYTOKEN=B77A5C561934E089类型.CryptoWinRT.exe 调用此 API.◦APIMSCORLIB 中的 System.Security.Cryptography.SHA256Managed.#ctor，此应用程序不支持 PUBLICKEYTOKEN=B77A5C561934E089类型.CryptoWinRT.exe 调用此 API.◦APISystem.Security.Cryptography.HashAlgorithm.ComputeHash(System.Byte[])在 MSCORLIB 中，不支持 PUBLICKEYTOKEN=B77A5C561934E089申请类型.CryptoWinRT.exe 调用此 API.

◦API System.Security.Cryptography.SHA256Managed in MSCORLIB, PUBLICKEYTOKEN=B77A5C561934E089 is not supported for this application type. CryptoWinRT.exe calls this API. ◦API System.Security.Cryptography.HashAlgorithm in MSCORLIB, PUBLICKEYTOKEN=B77A5C561934E089 is not supported for this application type. CryptoWinRT.exe calls this API. ◦API System.Security.Cryptography.SHA256Managed.#ctor in MSCORLIB, PUBLICKEYTOKEN=B77A5C561934E089 is not supported for this application type. CryptoWinRT.exe calls this API. ◦API System.Security.Cryptography.HashAlgorithm.ComputeHash(System.Byte[]) in MSCORLIB, PUBLICKEYTOKEN=B77A5C561934E089 is not supported for this application type. CryptoWinRT.exe calls this API.

这个的替代品是什么?为什么WinRT不允许这种微不足道的事情呢?

What is the replacement for this? And why would such a trivial thing not be allowed in WinRT?

推荐答案

这对你有用吗?

    private void HandleHashClick(object sender, RoutedEventArgs e)
    {
        // get the text...
        var inputText = this.textInput.Text;

        // put the string in a buffer, UTF-8 encoded...
        IBuffer input = CryptographicBuffer.ConvertStringToBinary(inputText, 
            BinaryStringEncoding.Utf8);

        // hash it...
        var hasher = HashAlgorithmProvider.OpenAlgorithm("SHA256");
        IBuffer hashed = hasher.HashData(input);

        // format it...
        this.textBase64.Text = CryptographicBuffer.EncodeToBase64String(hashed);
        this.textHex.Text = CryptographicBuffer.EncodeToHexString(hashed);
    }
