RE: OpenSSL in an embedded environment
I have (possibly) a similar problem. But just for the sake of completeness, is anyone aware of a port to VxWorks? If I could hook up with the poor sod that's been through this before that would probably save my hair at least. -lee __ OpenSSL Project http://www.openssl.org User Support Mailing List[EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]

Re: OpenSSL in an embedded environment
I am also thinking about to port openssl to an embedded system and noticed the the discussion. What sizes have you come down to ? and does your embeded system have filestorage ? fopen() or is the certificates stored in char []? The core question is what i takes to port it to an embeded system.

Re: OpenSSL in an embedded environment
My plan is to use OpenSSL to provide crypto for ucd-snmp (which uses des, md5, and sha) and ssl for a web server (using rsa, 3des, and sha or md5). I will also use it for certificate generation. I'm going to do some code and makefile editing to get rid of everything else I can, which I think includes bf, dh, dsa, hmac, idea, md2, md4, mdc2, pkcs7, rc2, rc4, rc5, and ripemd. Does that sound reasonable? >From: Dr S N Henson Subject: Re: OpenSSL in embedded environment Date: Sat, >28 Apr 2001 13:45:09 -0700 > >You may well have some 'fiddling' to substantially reduce the size of >OpenSSL.
