public class PemOutputStream

extends Base64OutputStream

This stream can be used to convert a binary DER output stream to a PEM style base64 encoded output stream. The result written to the underlying stream will look something like:

 -----BEGIN RSA PRIVATE KEY-----
 Base64 encoded data
 -----END RSA PRIVATE KEY-----
 

All lines will be terminated by '\n'.

Constructor Detail

PemOutputStream

public PemOutputStream(java.io.OutputStream out,

                       java.lang.String lastLine)
                throws java.io.IOException

Creates a new PemOutputStream.

Parameters:

out - a stream of DER encoded data

firstLine - the first line in the stream to write

lastLine - the last line in the stream to write

Throws:

java.io.IOException - if occurs an I/O error while writing the first line

Method Detail

flush

public void flush()
           throws java.io.IOException

Flushes the stream and writes the last line. This methos also ensures that flush() is only called for one time to avoid writing the last line for several times.

Overrides:
