PEM API github repo

[Anthony Scarpino]

Hi,

The following github link is to the PEM API as it is written in the 
draft JEP (https://openjdk.org/jeps/8300911).  There has been a few 
changes since the original posting.

https://github.com/ascarpino/jdk/tree/pem

The Encoder and PEMEncoder to now return byte[] for the encode() method. 
  A new PEMEncoder method, encodeToString(), was added.  I believe these 
make it easier for outputting data to a file and InputStreams, while 
still supporting a method that returns a String.

For decode, InputStream has replaced Reader.  There were comments 
preferring InputStream and I found that Reader's buffering quirks were 
problematic. Decoding from a byte[] is easy through an ByteArrayInputStream.

If you are interested in testing out the API, please download and 
compile the repo.  Then let me know how your experience went.

thanks

Tony
