Someone else will know more about this. People are working on it I think but it's not there yet. > 2. OCF has been ported to Linux, so will OCF integrate with Linux Crypto API > or not? OCF has a driver called cryptosoft that uses the linux crypto API. [leo]: thanks a lot.

Otherwise Once linux has it's own user space API you will not need OCF to provide one, but you will need to add/wait for support for applications like openssl etc to use the linux API. [leo]: This user space API you referred is the standard API on Linux, or the POSIX APIs? I googled and can NOT find it. Can you give me further more guide for it? So i think the framework looks like below, is it right? |-------------------------------------------------| | Linux User space Crypto API | User Space |-------------------------------------------------| ^ ------------------------|--------------------------------------------------------------------------------------- v |-------------------------------------------------|------------------------------------------- | Kernel Space | Dedicated Device Driver for it |Linux Crypto API | => this is the API maintained by Herbert in kernel space |-------------------------------------------------|--------------------------------------------| Cheers, Davidm -- David McCullough, david_mccullo...@securecomputing.com, Ph:+61 734352815 McAfee - SnapGear http://www.snapgear.com http://www.uCdot.org
