public PEMReader(File in)
          throws FileNotFoundException

Method Detail

readObject

public static Object readObject(File in)
                         throws FileNotFoundException,
                                IOException

Return single object from PEM file.

The first object will be returned, others are discarded.

Throws:

FileNotFoundException

IOException

readObject

public Object readObject()
                  throws IOException

This method also invalidates the password when an IOException occurs and throws a PasswordCancelledException when the user cancelled the password entry.

This method accepts garbage before and after any PEM blocks (outside of BEGIN/END). BouncyCastle 1.46 does not accept this (earlier versions do).

Currently uses BufferedReader.mark(int) and BufferedReader.reset(), so these cannot be used by calling code, sorry.

Overrides:

readObject in class PEMReader

Throws:

IOException
