# Can i get a list of over hard and long RSA keys? i think i have found a vulnerability in RSA Algorithm [closed]

al-right, I need some examples of hard and long RSA keys cause i think i have found vulnerability in RSA. i need you to give me few hard Values of n (which is pxq) and i will tell you what p and q are(don't tell me p and q, just tell me n) PLEASE I NEED TO SEE IT!

• I think this question uniquely qualifies for the "too broad" close reason: there are (literally) an infinite number of possible answers. – Reid May 20 '15 at 3:26

• Sorry, but unless you have discovered a new branch of mathematics, it is overwhelmingly likely that you have not found a way to quickly factor large primes. – Stephen Touset May 20 '15 at 4:20
• I have found a vulnerability in RSA, too. For example, I can factor $21 = 3\times 7$. I just have to deal with the last thingie: how to apply it to very, very big numbers. That's it. – fkraiem May 20 '15 at 8:43
• You can retrieve certificates from google with the openssl (and sed) commands: "openssl s_client -connect www.google.com:https < /dev/null | sed -ne '\/-----BEGIN CERTIFICATE-----/,\/-----END CERTIFICATE-----/p' | openssl x509 -noout -modulus" – Steve Peltz May 21 '15 at 5:05

Here's a 2048-bit modulus $n$:

• @user3651521: Yes. That is $n=pq$ where $p,q$ are distinct primes roughly 1024 bits in size. – Reid May 20 '15 at 1:31
