  OpenSsl Private Key Reverse Engineering question         


Author: Abhishek Kabra
Date: Jul 23, 2008 05:59

Hi All,

This question is related with Reverse Engg of private key. I have build
my application, which encrypt a fie based on pre defined private key.
The private key is in text file & it start with 0x30,0x82,0x04 ... . My
application converts private key in text format to EVP_KEY format using
d2i_PrivateKey_bio function. After it I use openSsl library standard
function to encrypt my file. This text file is basically ASN encoding
of the certificate (private key in DER format).

Is it possible to get a certificate embedded with the same private key
(or public /private pair) based on the private key in ASN encoding. I am
not sure if I am phrasing my question correctly. I want to get private
key in pem/der format from ASN encoded text file. (I want to use openSSL
tool, which runs over linux shell or cygwin)

I have done bit of goggling but didn't get any clue. I am new bie in
openssl. Let me know if you have some pointers for the same

Thanks/Regards
Abhishek

  Implementation of function RAND_Poll on VxWorks         


Author: Anuradha Gupta
Date: Jul 22, 2008 22:14

Hi

What shall be the implementation of function RAND_Poll on VxWorks. It is an empty function in my code just returning success.
In the UNIX flavour the same sets the entropy. On VxWorks, the entropy is not set this being empty function which results into ssl_connect failure.

Regards

just in case it helps debugging, when you said the first 8 bytes are wrong,
instead of trying a pattern like "1111111" to send over you might try
something like "12345..." so that way you can tell WHERE your data is
getting messed up - ie that could show that not only is the first 8 bytes
wrong, but your data begins at byte 9, which could point to a padding issue
or something like that.

my 2 cents in case it helps debugging (:

hello

I downloaded OPENSSL because I was getting an error message:
stunnel-4.10.exe-ordinal not found
I am not getting that message anymore but now I am getting this message upon startup:
stunnel-4.10.exe.-application error
the application failed to initialize properly (0xc0150002). click to terminate the application.
Do you know how I can fix this??

  OpenSSL::PKey::RSAError: Neither PUB key nor PRIV key:: header too long         


Author: Michael Tracey Zellmann
Date: Jul 22, 2008 09:35

I am getting this error when I try to use some ruby OepnSSL libraries
to obtain the private key from my private key PEM file.

I have tried this on the SSL credentials I got for my web-site from
GoDaddy.com - The site works fine and credentials are recognized in IE
and FF.

I tried generating my own RSA key directly on my Mac - to avoid any
possibility of errors on transferring.

I ran this command on the Mac
openssl genrsa -out privkey.pem 1024

Then I ran this command in a ruby rails development console where f is
the file holding the private key
key = OpenSSL::PKey::RSA.new(f.read)

Then I ran this command to generate a self-signed certificate
openssl req -new -x509 -key privkey.pem -out cacert.pem -days 1095

Just to try it, I also tried it pointing to the certificate file

In both instances, I get the same error message

  Disabling the PKCS #11 on Solaris 10         


Author: sadronmeldir
Date: Jul 22, 2008 05:30

Hello all,

I'm aware that the default installation of the Solaris 10 OS provides a
PKCS#11-based OpenSSL implementation. I'm trying to take some metrics to
figure out how much more efficient certain processes are with the PKCS
engine. How would I disable the PKCS engine on an UltraSPARC T1 processor?
