SetOutputStream Method

The stream to which the component will write the fully encrypted or decrypted OpenPGP data.

procedure SetOutputStream(OutputStream: TStream);

Remarks

This method sets the stream to which the component will write the fully encrypted or decrypted OpenPGP data. If an output stream is set before the component attempts to encode or decode an OpenPGP message, the component will write the data to the output stream instead of populating OutputMessage or writing to OutputFile.

Sign and/or Encrypt

To sign and/or encrypt a message to an output stream, you must first populate the Message property with the data you would like to sign and/or encrypt. Next, this method must be called with a valid output stream for which the component may write the signed or encrypted data. Then call Sign, Encrypt, or SignAndEncrypt to sign and/or encrypt the message. The appropriate ASCII Armor headers will be generated in MessageHeaders.

Decrypt and/or Verify

If you would like to decrypt a message or verify its signature and write the resulting message to an output stream, you should set the Message property to the signed and/or encrypted message you would like to verify or decrypt. Next, you must call this method to specify a valid stream for the component to write the data to. Then call VerifySignature, Decrypt, or DecryptAndVerifySignature to verify and/or decrypt the message.

Input and Output Properties

The component will determine the source and destination of the input and output based on which properties are set.

The order in which the input properties are checked is as follows:

When a valid source is found the search stops. The order in which the output properties are checked is as follows:

  • SetOutputStream
  • OutputFile
  • OutputMessage: The output data is written to this property if no other destination is specified.

When using streams you may need to additionally set CloseInputStreamAfterProcessing or CloseOutputStreamAfterProcessing.
