System: NetBSD swinger.shagadelic.org 1.6X NetBSD 1.6X (SWINGER) #15: Tue Aug 26 15:43:43 PDT 2003  thorpej@yeah-baby.shagadelic.org:/u1/netbsd/src/sys/arch/i386/compile/SWINGER i386

>Description:
	opencrypto has a design flaw in that it only operates in-place,
	i.e. it cannot perform an operation where the source buffer and
	the destination buffer are different.  This requires applications
	that need to use different source and destination buffers to
	copy the data to destination buffer before the crypto operation.
	This is inefficient; the data could be copied while the crypto
	operation is taking place.

>How-To-Repeat:
	Attempt to use opencrypto with an application that uses different
	buffers for source and destination with a crypto operation.

>Fix:
	Infrastructure and API changes will be required in order to
	address this issue.
