Owen O'Malley commented on HADOOP-10149:
----------------------------------------
Afterr looking at the javax.security.Cipher API more deeply, it does have both
byte[] and ByteBuffer methods.
Unfortunately the methods in Cipher are declared final and the actual
implementation is done by a nested implementation class. It isn't clear what
the performance penalty for using javax.security.Cipher with a openssl-based
provider would be, but it doesn't look excessive.
My thoughts are that instead of reinventing the wheel, we should use the
standard javax.security.Cipher API with a customer provider that is based on
openssl.
Thoughts?

> As part of HDFS-5143, [~hitliuyi] included a ByteBuffer-based API for
> encryption and decryption. Especially, because of the zero-copy work this
> seems like an important piece of work.
> This API should be discussed independently instead of just as part of
> HDFS-5143.
