comment What type of encryption is this?
You could try to find what the encryption scheme was (assuming it is encryption). $\;$

comment SSL / TLS digital signature exchange
@HarshitBhatt : $\;\;\;$ Yes. $\:$ Does the server's public key count as one of the "details" of "the original certificate"? $\:$ ... Almost tautologically, "if they are not used anywhere" then there won't be a use for them. $\;\;\;\;\;\;\;$

comment Why is the call to RSA_generate_key_ex() failing sometimes?
I'm voting to close this question as off-topic because it is a programming problem. You should ask on stackoverflow.com a version of this question that specifies which programming language you are using.

comment Asymmetric encryption that is secure for (almost) any foreseeable future
@HadrienG. : $\;\;\;$ No, since there isn't even a known proof that there is no extremely practical algorithm for QBFs. $\:$ There is a complete PKE scheme, but it's completely impractical. $\;\;\;\;\;\;\;\;$

comment Asymmetric encryption that is secure for (almost) any foreseeable future
"Security is broken if an attacker can ... or reliably forge a message that looks like it has $\hspace{1.1 in}$ been encrypted with the private key" is an odd criterion. $\;$

comment What are the difference between cryptographic primitives and encryption primitives?
@StephenTouset : $\;\;\;$ They are only properties of implementations in the context of defending against physical-access side-channel attacks. $\:$ Otherwise, they are desirable properties of the ciphers themselves. $\;\;\;\;\;\;\;\;$

comment Question about feistel network
Does anything nearby mention that? $\:$ If no, then I'd guess your answer should be in terms of the round function. $\;\;\;\;$
