Re: PKCS#7

Hi,

thank you very much for your response.

Say someone would be able to gather several clear text AES keys and their respective asymmetrically encrypted RSA blocks. Would it weakens the security of the RSA key pair ? I mean could it be easier for someone using that information to brute force an RSA key pair ?

Thank you

Yes.  But maybe not with the openssl api's :)
