openssh unix dev - Nov 2001 - Embedded Cross-Compiling of OpenSSL & OpenSSH

I'm developing a minimal embedded linux system that will be running on a
powerpc chip.  I can get everything to work but the size is quite large.

The majority of my size requirements are in libcrypto.a which is around
1.52 Megs

I tried to pare it down further by removing some crypto options
[ Configure linux-ppc no-asm no-cast no-des no-dh no-md2 no-mdc2 no-rc2
no-rc4 no-rc5 shared ]
This got me to 1.35 Megs.

I've read on other lists that stripping the library is bad news, but a
modest debug strip doesn't seem to affect functionality and takes me
down to 800 K.

Any ideas on how I can get libcrypto smaller?

Thanks,

These questions would probably be better asked on one of the OpenSSL 
lists.

You may want to keep rc4 for OpenSSH - it is used in several places and the
algorithm itself is tiny.

I can't see why stripping should cause any problems.
