Removed your email and Facebook id's. NEVER post this kind of stuff in a public forum unless you like to receive huge amounts of spam.

All communication on this question will happen here in the forums, not privately.

how does using a public key make it vulnerable, and why does using the private key resolve this? it's asymmetric - you're robbing peter to pay paul!

I have a piece of advice: forget this idea and find a project that you do at least have some idea about.

And no, it's not "urgent" for the unpaid volunteers who answer questions here. Adding "urgent" to your question titles simply encourages us to ignore your question.

As others already pointed out, the sentence

Quote:
using Public key for communication so it is vulnerable

is just wrong.

Have a look at this Wikipedia page "Public-key cryptography"[^].
