Class ArmoredOutputStream

java.lang.Object

java.io.OutputStream

org.bouncycastle.bcpg.ArmoredOutputStream

All Implemented Interfaces:

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

public class ArmoredOutputStream
extends java.io.OutputStream

Output stream that writes data in ASCII Armored format.

Note 1: close() needs to be called on an ArmoredOutputStream to write the final checksum. flush() will not do this as other classes assume it is always fine to call flush() - it is not though if the checksum gets output. Note 2: as multiple PGP blobs are often written to the same stream, close() does not close the underlying stream.

Constructor Detail

ArmoredOutputStream

public ArmoredOutputStream(java.io.OutputStream out)

Constructs an armored output stream with default headers.

Parameters:

out - the OutputStream to wrap.

ArmoredOutputStream

public ArmoredOutputStream(java.io.OutputStream out,
                           java.util.Hashtable headers)

Constructs an armored output stream with default and custom headers.

Parameters:

out - the OutputStream to wrap.

headers - additional headers that add to or override the default headers.

Method Detail

setHeader

public void setHeader(java.lang.String name,
                      java.lang.String value)

Set an additional header entry. Any current value(s) under the same name will be replaced by the new one. A null value will clear the entry for name.

Parameters:

name - the name of the header entry.

value - the value of the header entry.

addHeader

public void addHeader(java.lang.String name,
                      java.lang.String value)

Set an additional header entry. The current value(s) will continue to exist together with the new one. Adding a null value has no effect.

Parameters:

name - the name of the header entry.

value - the value of the header entry.

resetHeaders

public void resetHeaders()

Reset the headers to only contain a Version string (if one is present)

beginClearText

public void beginClearText(int hashAlgorithm)
                    throws java.io.IOException

Start a clear text signed message.

Parameters:

hashAlgorithm -

Throws:

java.io.IOException

endClearText

public void endClearText()

write

public void write(int b)
           throws java.io.IOException

Specified by:

write in class java.io.OutputStream

Throws:

java.io.IOException

flush

public void flush()
           throws java.io.IOException

Specified by:

flush in interface java.io.Flushable

Overrides:

flush in class java.io.OutputStream

Throws:

java.io.IOException

close

public void close()
           throws java.io.IOException

Note: close() does not close the underlying stream. So it is possible to write multiple objects using armoring to a single stream.

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Overrides:

close in class java.io.OutputStream

Throws:

java.io.IOException
