Recovery of parent private key from parent xpub and child’s private key
Implement recovery attack
Use AsRef<str>
Optimization patch
Optimize key derivation
Handle invalid curve point during derivation
Overview
Although the probability is extremely low (one in 2^127), bip32 CFD function would produce invalid private key or public key. bip39 spec requires implementer to handle this edge case.
xprv child derivation
https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki#private-parent-key--private-child-key
In case parse256(IL) ≥ n or ki = 0, the resulting key is invalid, and one should proceed with the next value for i. (Note: this has probability lower than 1 in 2127.)
xpub child derivation
https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki#private-parent-key--private-child-key
In case parse256(IL) ≥ n or Ki is the point at infinity, the resulting key is invalid, and one should proceed with the next value for i.
