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()
