Class PemOutputStream

java.lang.Object

java.io.OutputStream

java.io.FilterOutputStream

iaik.utils.Base64OutputStream

iaik.utils.PemOutputStream

All Implemented Interfaces:

java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable

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

Creates a new PemOutputStream to write PEM encoded data to the specified underlying output stream.

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

PemOutputStream

public PemOutputStream(java.io.OutputStream out,
               java.lang.String firstLine,
               java.lang.String lastLine,
               byte[] lineBreak)
                throws java.io.IOException

Creates a new PemOutputStream to write PEM encoded data to the specified underlying output stream. Each line is finsihed by the given line break delimiter.

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

lineBreak - - the lineBreak the line break delimiter to be used; if null, the currently static set line break delimiter CRLF (0x0D, 0x0A) will be used

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.

Specified by:

flush in interface java.io.Flushable

Overrides:

flush in class Base64OutputStream

Throws:

java.io.IOException - if there occurs an I/O error
