[Eli Brin]

Hello,

We are working with ELDK 2.0.2, target - TQM860L

We are trying to work with openssl, and we have the following problems:

1.  Trying to create a certificate using the CA script gives us the
following error:
>sh-2.05$ ./CA -newca
>CA certificate filename (or enter to create)

>Making CA certificate ...
>Using configuration from /usr/share/ssl/openssl.cnf
>unable to load 'random state'
>This means that the random number generator has not been seeded
>with much random data.
>Generating a 1024 bit RSA private key
>403:error:24064064:random number generator:SSLEAY_RAND_BYTES:PRNG not
seeded:md_
>rand.c:492:You need to read the OpenSSL FAQ,
http://www.openssl.org/support/faq.

We don't have the /dev/random and /dev/urandom. How do we create them -
mknod?


2.  Using pem files created on a Redhat Linux machine gives us an error on
the function:
ssl_ctx_use_certificate_chain_file.

Should we create the pem files on our target or those created with Redhat
are OK?


Our application works OK with openssl on RH8.0 and RH7.3.

Has anyone worked successfully with openssl on  ppc_8xx?

Thank you,
Eli Brin

Yes,

  mknod /dev/random  c 1 8
  mknod /dev/urandom c 1 9

is all you need to do.

Umm... maybe. Note that you might end up waiting for a LONG  time  to
get any data out of /dev/random...

it's not that trrivial. Normally, many sources  of  "ramdomness"  are
used to generate input for the random device, like key presses on the
keyboard,  mouse movements, etc. Most of this is simply not available
in an embedded system. You will have to tweak this a bit...

I have a theory that it's impossible to prove anything, but  I  can't
prove it.

Hello,

Just for the record:

We are working successfully with openssl 0.9.7a (ssl_v2, ssl_v3, tls_v1) on
the ELDK and Embedix running on TQM860L and FADS860T.

The older versions 0.9.6b-xx had problems and worked partly with ssl-v2
only.

The performance it not so great...but I think it can be improved with RTAI
(we use HZ=1000).

Thanks Coray (Lineo) for the help.

Best Regards,
Eli Brin
