I did go thru a lot of articles which say's It's highly impossible to break the bitcoin public-key and get a private key from it. I understand that the public key does hold some info of it's corresponding private key. Can anyone suggest me some steps for manual calculation and reversing the scalar multiplication from the public key so I obtain the private key? I'm not looking for any scripts for doing this but I'm looking for mathematical steps in-order to reverse the public key to private key.

  • The mathematical steps that you ask for are those required for breaking the public key cryptography system. Currently, those steps are unknown. – Willtech Jan 29 '18 at 12:11

I think this can serve as a start point.


This is simply practically not possible; it's one of the basic premises of public-key cryptography:

The strength of a public key cryptography system relies on the computational effort (work factor in cryptography) required to find the private key from its paired public key. If so, effective security only requires keeping the private key private; the public key can be openly distributed without compromising security.

Unless somebody breaks the cryptographic algorithm used to generate the keys, your best bet is to simply generate random keys and check whether the corresponding public key matches the one you already have. (Well, that's a slight exaggeration but you get the point.)

  • Yes, brute force the private key and check if generated public keys match is about the only conceivable method presently. – Willtech Jan 29 '18 at 12:10

I think its not possible to get back the public key, someone would have applied supercomputing power to get back all the bitcoins and become super rich.
