Access to an xpub does not give access to child private keys. However, because the xpub contains the chain code, if a child private key is known, or somehow leaked, it can be used with the chain -code to derive all the other child private keys. A single leaked child -private key, together with a parent chain code, reveals all the private -keys of all the children.

A single leaked child private key, together with a parent chain code, can be used to deduce the parent private key. As a result, all of the child private keys of the parent are compromised. To counter this risk, HD wallets provide an alternative derivation function called _hardened derivation_, which breaks the relationship between diff --git a/meta/github_contrib.adoc b/meta/github_contrib.adoc index 6bb33810..ff55bd57 100644 --- a/meta/github_contrib.adoc +++ b/meta/github_contrib.adoc @@ -168,6 +168,7 @@
