示例1: EncryptData

Private Shared Sub EncryptData(inName As String, outName As String, _
rijnKey() As Byte, rijnIV() As Byte)

    'Create the file streams to handle the input and output files.
    Dim fin As New FileStream(inName, FileMode.Open, FileAccess.Read)
    Dim fout As New FileStream(outName, FileMode.OpenOrCreate, _
       FileAccess.Write)
    fout.SetLength(0)
    
    'Create variables to help with read and write.
    Dim bin(100) As Byte 'This is intermediate storage for the encryption.
    Dim rdlen As Long = 0 'This is the total number of bytes written.
    Dim totlen As Long = fin.Length 'Total length of the input file.
    Dim len As Integer 'This is the number of bytes to be written at a time.
    'Creates the default implementation, which is RijndaelManaged.
    Dim rijn As SymmetricAlgorithm = SymmetricAlgorithm.Create()
    Dim encStream As New CryptoStream(fout, _
       rijn.CreateEncryptor(rijnKey, rijnIV), CryptoStreamMode.Write)
    
    Console.WriteLine("Encrypting...")
    
    'Read from the input file, then encrypt and write to the output file.
    While rdlen < totlen
        len = fin.Read(bin, 0, 100)
        encStream.Write(bin, 0, len)
        rdlen = Convert.ToInt32(rdlen + len)
        Console.WriteLine("{0} bytes processed", rdlen)
    End While
    
    encStream.Close()
fout.Close()
fin.Close()
End Sub
