Class org.bouncycastle.openpgp.PGPEncryptedDataGenerator

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

org.bouncycastle.openpgp.PGPEncryptedDataGenerator.open()
If buffer is non null stream assumed to be partial, otherwise the length will be used to output a fixed length packet.
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 @param length @param buffer @return @throws IOException @throws PGPException @throws IllegalStateException
