C# 如何使用OpenPGP从一个blob解密到另一个blob

我每天将几个PGP加密文件导入blob存储。我需要能够将它们解密到同一blob容器中的另一个位置

我已经知道我必须在ADF中创建一个定制的批处理活动来完成这项工作，我只是不知道如何将blob发送到OpenPgp

来自bitscry.com的示例代码建议使用流作为示例：

using (FileStream inputFileStream = new FileStream(@"C:\TEMP\keys\content__encrypted2.pgp", FileMode.Open))
using (Stream outputFileStream = File.Create(@"C:\TEMP\keys\content__decrypted2.txt"))
using (Stream privateKeyStream = new FileStream(@"C:\TEMP\keys\private.asc", FileMode.Open))
    pgp.DecryptStream(inputFileStream, outputFileStream, privateKeyStream, "password");

我试着把这些斑点当作溪流打开，但它不起作用

这是尝试将blob用作流的代码：

        Stream sourceStream = keyBlockBlob.OpenRead();
        Stream keyStream = sourceCloudBlockBlob.OpenRead();
        Stream targetStream = targetCloudBlockBlob.OpenWrite();

        pgp.DecryptStream(sourceStream, targetStream, keyStream, "password");

我知道我做错了什么。在传递到解密流之前，我没有将流位置重置为零。此代码适用于：

        var sourceStream = new MemoryStream();
        var keyStream = new MemoryStream();
        var targetStream = new MemoryStream();

        sourceCloudBlockBlob.DownloadToStream(sourceStream);
        sourceStream.Position = 0;

        keyBlockBlob.DownloadToStream(keyStream);
        keyStream.Position = 0;


        pgp.DecryptStream(sourceStream, targetStream, keyStream, "password");
        targetStream.Position = 0;
        targetCloudBlockBlob.UploadFromStream(targetStream);
