@Kerlingen & Storm
I see the public key similar as below(but for my case, it's 2048bit), so whether means it's SSL Cert? If yes, whether have chance to break? Thanks.

-----BEGIN PUBLIC KEY-----

Dear Kelingen,

Sorry, I missed this post. Yes, I found the public key when did dynamic debug(thanks Storm's help).

It's 2048bit RSA, I have verified the public key with manual caculation by bigcal tool for (m^e)mod(n), the public key is right.

If use openssl RSA, not sure whether have chance to get the private key?

From Storm: it is fully possible to find rsa signatures from memory http://www.trapkit.de/research/sslkeyfinder/keyfinder_v1.0_20060205.pdf , maybe have chance.
