All Implemented Interfaces:

Closeable, AutoCloseable, Readable

public class PKCS8DERReader
extends org.bouncycastle.openssl.PEMParser

This class extends the PEMParser class from the BC library. It is modified to read DER input, not the PEM (it can be considered a smart-hack) as otherwise BC's parsers code would need to be copied. It supports reading of the PKCS8 private key in DER form. It is assumed that the key is encrypted if a password is provided.

This class interface is the readObject method.

This implementation overrides the PemReader readPemObject method to actually read the DER. The Reader used by the PemReader is not used.
