hi all:
My quesitons about openssl are below:
1. I want to take advantage of RSA and SHA in openssl for secure booting.
Can they run as standalone program, that means they can run without
libc support.
2. I want RSA and sha authentication run in DRAM instead of flash,
such that the speed will be
Look, the typical way you'd use the DH shared secret would be to hash
it using an appropriate hash function. I personally like using Tiger
with AES-192, YMMV.

IMHO openssl is unsuitable for this purpose. Openssl is really good
at what it does, don't get me wrong, but using it in a boot loader
probably isn't the easiest/smartest idea. What you really want is a
subset of PKCS#1 - that is, EMSA-PSS encoding and verification plus

Hi,
I have done the RSA encryption program. Now I want to convert that encrypted
message to BASE64 message inorder to send the message via socket.
I am trying the following sample code which converts Hello World to Base64
format and *printing in console* ( stdout).

Hello,
I am having really problems to get a big number printed out in the stdout...
This is how it should be (if I got it properly):
*BIGNUM *r;*
*BIO *out;*
*
*
*out = BIO_new_fp(stdout, BIO_NOCLOSE);*
*
*
*r=BN_new();*
*

*BN_rand(r, 2048, -1, 0)*

*BN_print(out, r);*
but when I

Hi All,
I am trying in vain to find out why the AES decrypt won't work here.
I have found where exactly is the problem and now looking for some
wise-crack to help me solve it.
Here is the code that I tested with(from various posts here):
#include string.h
#include stdio.h

I'm pretty new to this PKI stuff, but I'm very confused about why pkcs12 files
are encrypted.
As I understand it, a basic p12 file contains within it two things:
(1) A private key (private.pem in my case, an RSA key created with genrsa)
(2) An x509 certificate (cert.pem in my case, created with

Ikuzar,
I'm not sure what software you're writing. Please understand that I'm
not trying to be mean spirited when I say this, but if you don't
already know the difference between symmetric vs public-key crypto
then you should not be writing this type of code. Stop doing it until
you have a firm

Hi all,
I'm having a problem using ecdsa with SHA 384 when creating a message
digest. I will admit I'm not too familiar with openssl and digests, but
I have code that works using -ecdsa-with-SHA1. I need to change that to
use ecdsa-with-SHA384. I looked at the release notes to see that this
