'Usage

void DecryptStream(
    int SessionHandle,
    string StreamName,
    Object EncryptedStream,
    Object UnencryptedStream
)

Parameters

• SessionHandle
  Type: System.Int32

  The ID of the current session.

  The ID of the stream of data.

  The encrypted data stream.

Remarks

This method is called by your COM add-in when the document is opened, and after your add-in has verified that the user opening the document is authenticated. This method is the inverse of EncryptStream(Int32, String, Object, Object) method and converts encrypted data back into pure (un-encrypted) data.
