OpenSSL ENIGNE support for OpenSSH

[Michal Ludvig]

Hi all,

attached is a patch that enables using hardware crypto accelerators
available through OpenSSL library for SSH operations. Especially in
ssh/sshd it can bring a significant speed improvement. OTOH if no crypto
engine is available, nothing bad happens and default software crypto
routines are used.

This patch is used in SUSE Linux OpenSSH package and proved to work (at
least it didn't break anything) both with and without crypto engines.
Tested also with VIA PadLock crypto engine (patches for OpenSSL are at
http://www.logix.cz/michal/devel/padlock/ )

Would you consider including it in the official OpenSSH release?

Thanks!

Michal Ludvig
