Title: "Exposing a single private key can compromise your entire wallet!"
Post by: anti-scam on June 23, 2017, 03:14:09 PM
Is it true that a deterministic wallet's seed (or master private key or equivalent) can be recovered completely from just one of the private keys that it created? Is this a guaranteed every time sort of thing, or a probabilistic thing, or what?

You need the master public key + one private key.

It would pay great dividends if everyone took a serious look at the thread linked in this post.  I see lots of private keys being moved around here and frankly it scares me some.  I don't do it but I am a "paranoid" user where security is concerned.  This thread shows how a private key is maybe one step behind someone having your SEED.
