Subject [jira] Commented: (AXIS2C-272) encryption/decryption should work on streams
Date Tue, 12 Dec 2006 19:00:21 GMT
    [ http://issues.apache.org/jira/browse/AXIS2C-272?page=comments#action_12457843 ] 
            
James Clark commented on AXIS2C-272:
------------------------------------

Your solution is inefficient.  Apart from inefficiency, it's wrong from a modularity point
of view.  There's nothing security specific in oxs_buffer.  There should be a single byte
stream abstraction used throughout the code base, which means it belongs  in util not in rampart.
A byte stream abstraction is needed because the parser needs to be able to operate directly
on the result of the decryption without an additional copy.  Using a single array for the
entire decrypted result is bad, because you can't stream (i.e. you have to keep all of both
the encrypted and decrypted text in memory), and you'll do lots of copies and reallocations.

Maybe now is not the right time to fix it, but the issue is not by any stretch of the imagination
"resolved".

It's really not a good approach for each developer to create their own personal utility libraries
in the subsystems they're responsible for.

> axis2_output_stream_t *create_encryption_stream(..., axis2_output_stream *encrypted_stream)
> Writing output on the returned stream should cause the corresponding binary (not base64-encoded)
encrypted bytes to be written to encrypted_stream.
> Similarly, for decryption
> axis2_input_stream *create_decryption_stream(..., axis2_input_stream *encrypted_stream)
