java.io.OutputStream

java.io.FilterOutputStream

google.registry.rde.RydeEncoder

All Implemented Interfaces:

Closeable, Flushable, AutoCloseable

@NotThreadSafe
public final class RydeEncoder
extends FilterOutputStream

Stream that performs the full RyDE encryption.

The RyDE format has 2 files:

• the "data" file, encoded in data -> tar -> PgpFile -> compression -> encryption
• the signature of the resulting file

Hence, the encoder needs to receive 2 OutputStreams - one for the data and one for the signature.

Because of the external tar file encoding - the encoder must know the total length of the data from the start. This is a bit annoying, but necessary.

Method Details

write

public void write(byte[] b,
 int off,
 int len)
           throws IOException

Call the underlying 3 input write.

FilterInputStream implements the 3 input write using a for loop over the single-byte write. For efficiency reasons, we want it to use the 3 input write instead.

Overrides:

write in class FilterOutputStream

Throws:

IOException

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class FilterOutputStream

Throws:

IOException
