addMethod
public void addMethod(char[] passPhrase)
throws NoSuchProviderException,
PGPException
Add a PBE encryption method to the encrypted object.
addMethod
public void addMethod(PGPPublicKey key)
throws NoSuchProviderException,
PGPException
Add a public key encrypted session key to the encrypted object.
close
public void close()
throws IOException
Close off the encrypted object.
open
public OutputStream open(OutputStream out,
byte[] buffer)
throws IOException,
PGPException
Return an outputstream which will encrypt the data as it is written
to it. The stream will be written out in chunks according to the size of the
passed in buffer.
Note: if the buffer is not a power of 2 in length only the largest power of 2
bytes worth of the buffer will be used.
out
- buffer
- the buffer to use.
open
public OutputStream open(OutputStream out,
long length)
throws IOException,
PGPException
Return an outputstream which will encrypt the data as it is written
to it.
