There was a problem hiding this comment.
fixed here:
- we allow to de-serialize extended public key that contains private key and vice-versa (we haven't checked the version vs data inside)
- we allow to de-serialize extended public that contains invalid secp256k1 pubkey, for example
020000000000000000000000000000000000000000000000000000000000000007(not a security issue here as invalid pubkey would raise exception when we start working with it, but this imo should be part of validation logic)
…ed key has proper version wrt data it carries
