[jira] [Commented] (HADOOP-10151) Implement a Buffer-Based Chiper InputStream and OutPutStream

["Owen O'Malley (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-10151?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13843332#comment-13843332 ] 

Owen O'Malley commented on HADOOP-10151:
----------------------------------------

After looking more at the Cipher API, it does in fact have ByteBuffer methods, but the methods on Cipher are final and it delegates to an underlying implementation object. Having a direct implementation will be much more efficient.

> Cipher InputStream and OuputStream are buffer-based, and the buffer is used to cache the encrypted data or result.   Cipher InputStream is used to read encrypted data, and the result is plain text . Cipher OutputStream is used to write plain data and result is encrypted data.
