Searching for X.509 Public Key Infrastructure Certificates
Searching for PKCS #8: Private-Key Information Syntax Standard
Key scan complete.

public key for attached demo case:
n=80C07AFC9D25404D6555B9ACF3567CF1, e=10001

the script searches for the public rsa key header in certicates as shown here.

it wouldent find anything in the demo case( source for your file here) http://read.pudn.com/downloads149/sourcecode/crypt/645649/KeyGen/src/RSAKeyGen.c__.htm
it cant find random public keys

Dear Storm,

I'm inspired with the document your gave "OpenSSL 1024 bit RSA Private Key Breakdown". I see the public key before when do dynamic debug with edb(as the attached picture shows), but I don't understand it, after read the document, I fully understand it.

I still don't know how to make the rsa signature files, but with your help I have found and understand the public key, and have verify my understanding is right with BigCal. Here I should say many thanks to you for your warm help and guide.

I may still have some questions related, hope you can still give help, thanks again.
