This uses coincurve as a wrapper for libsecp256k1, which you may have already installed anyway, for EC operations.
All public keys below are compressed.
All path below are a list of integers representing the index of the key at each depth.
classmethod
Instanciate from a raw seed (as bytes). See bip-0032's master key
generation.
classmethod
Instanciate with an encoded serialized extended private key (as str) as master.
classmethod
Instanciate with an encoded serialized extended public key (as str) as master.
You'll only be able to derive unhardened public keys.
Returns (chaincode (bytes), privkey (bytes)) of the private key pointed by the path.
Returns privkey (bytes), the private key pointed by the path.
Returns (chaincode (bytes), pubkey (bytes)) of the public key pointed by the path.
Note that you don't need to have provided the master private key if the path doesn't
include an index >= HARDENED_INDEX.
Returns pubkey (bytes), the public key pointed by the path.
Note that you don't need to have provided the master private key if the path doesn't
include an index >= HARDENED_INDEX.
Returns xpriv (str) the serialized and encoded extended private key pointed by the given
path.
Returns xpub (str) the serialized and encoded extended public key pointed by the given
path.
Note that you don't need to have provided the master private key if the path doesn't
include an index >= HARDENED_INDEX.
Equivalent to get_xpriv_from_path([]).
Equivalent to get_xpub_from_path([]).
