Class org.bouncycastle.openpgp.PGPCompressedDataGenerator

Examples of org.bouncycastle.openpgp.PGPCompressedDataGenerator.open()

org.bouncycastle.openpgp.PGPCompressedDataGenerator.open()
Return an OutputStream which will save the data being written to the compressed object.
The stream created can be closed off by either calling close() on the stream or close() on the generator. Closing the returned stream does not close off the OutputStream parameter out. @param out underlying OutputStream to be used. @return OutputStream @throws IOException , IllegalStateException

        PGPCompressedDataGenerator comData = new PGPCompressedDataGenerator(algorithm);
        OutputStream cos = comData.open(bOut); // open it with the final destination


        PGPLiteralDataGenerator lData = new PGPLiteralDataGenerator();


        // we want to generate compressed data. This might be a user option later,
        // in which case we would pass in bOut.
