Big Thank All of You !!! You get me axact information what I search.
So now it's your turn, what is your ultimate goal with this/these public keys? I'm sure it's not just so you can fire up some software...
Doesn't really matter, does it... I couldn't care less if the OP found a piece of software that promised him he could reverse engineer a private key starting from a public key.
Some people just need to learn the hard way, if he tries to reverse engineer a private key all he'll do is infect his pc with malware and/or waste a lot of his time... Doesn't have any impact on me either way
If he's just trying to learn, kudos to him... I can only encourage people that want to broaden their knowledge.
