示例1: File
private async static Task File(string inFile, string outFile, RSACryptoServiceProvider key)
{
using (AesManaged aesManaged = new AesManaged())
{
// Create instance of AesManaged for
// symetric encryption of the data.
aesManaged.KeySize = 256;
aesManaged.BlockSize = 128;
aesManaged.Mode = CipherMode.CBC;
using (ICryptoTransform transform = aesManaged.CreateEncryptor())
{
RSAPKCS1KeyExchangeFormatter keyFormatter = new RSAPKCS1KeyExchangeFormatter(key);
byte[] keyEncrypted = keyFormatter.CreateKeyExchange(aesManaged.Key, aesManaged.GetType());
// Create byte arrays to contain
// the length values of the key and IV.
byte[] LenK = new byte[4];
byte[] LenIV = new byte[4];
int lKey = keyEncrypted.Length;
LenK = BitConverter.GetBytes(lKey);
int lIV = aesManaged.IV.Length;
LenIV = BitConverter.GetBytes(lIV);
// Write the following to the FileStream
// for the encrypted file (outFs):
// - length of the key
// - length of the IV
// - ecrypted key
// - the IV
// - the encrypted cipher content
using (FileStream outFs = new FileStream(outFile, FileMode.Create))
{
await outFs.WriteAsync(LenK, 0, 4);

await outFs.WriteAsync(keyEncrypted, 0, lKey);

// Now write the cipher text using
// a CryptoStream for encrypting.
using (CryptoStream outStreamEncrypted = new CryptoStream(outFs, transform, CryptoStreamMode.Write))
{
// By encrypting a chunk at
// a time, you can save memory
// and accommodate large files.
int count = 0;
int offset = 0;
// blockSizeBytes can be any arbitrary size.
int blockSizeBytes = aesManaged.BlockSize / 8;

int bytesRead = 0;
using (FileStream inFs = new FileStream(inFile, FileMode.Open))

do
{
