示例1: using
byte[] imageBuffer;
using (Stream cipherTextStream = File.OpenRead(encryptedFile))
{
byte[] contentLengthByteBuffer = new byte[sizeof(Int32)];
// Read the length of the source content file
// from the first four bytes of the encrypted file.
ReliableRead(cipherTextStream, contentLengthByteBuffer,
0, sizeof(Int32));
// Allocate the clearText buffer.
int contentLength =
BitConverter.ToInt32(contentLengthByteBuffer, 0);
imageBuffer = new byte[contentLength];
// Allocate the cipherText block.
byte[] cipherTextBlock =
new byte[cryptoProvider.BlockSize];
// decrypt cipherText to clearText block by block.
int imageBufferIndex = 0;
for ( ; ; )
{ // Read cipherText block.
int readCount = ReliableRead(
cipherTextStream,
cipherTextBlock, 0,
cryptoProvider.BlockSize);
// readCount of zero is end of data.
if (readCount == 0)
break; // for
// Decrypt cipherText to clearText.
byte[] clearTextBlock =
cryptoProvider.Decrypt(cipherTextBlock);
// Copy the clearTextBlock to the imageBuffer.
int copySize = Math.Min(clearTextBlock.Length,
contentLength-imageBufferIndex);
Array.Copy(clearTextBlock, 0,
imageBuffer, imageBufferIndex, copySize);
imageBufferIndex += copySize;
}
}// end:using (Stream cipherTextStream = (close/dispose)
