the valid HD private node from which to derive the child node
the index at which to derive the child node - indexes greater
than or equal to the hardened index offset (0x80000000/2147483648) are
derived using the "hardened" derivation algorithm
an optional object containing implementations of sha256, ripemd160, secp256k1 compressed public key derivation, and secp256k1 private key "tweak addition" (application of the EC group operation)
Returns the ripemd160 hash of the provided input.
To incrementally construct a ripemd160 hash (e.g. for streaming), use
init, update, and final.
a Uint8Array to be hashed using ripemd160
Tweak a privateKey by adding tweakValue to it.
Returns an error message if the private key is invalid or if the addition fails.
a valid secp256k1 private key
256 bit value to tweak by (BE)
Derive a compressed public key from a valid secp256k1 private key.
Returns an error message if the provided private key is too large (see
validatePrivateKey).
a valid secp256k1, 32-byte private key
Returns the sha256 hash of the provided input.
To incrementally construct a sha256 hash (e.g. for streaming), use init,
update, and final.
a Uint8Array to be hashed using sha256
Returns the sha512 hash of the provided input.
To incrementally construct a sha512 hash (e.g. for streaming), use init,
update, and final.
a Uint8Array to be hashed using sha512

Derive a child HD private node from an HD private node.
To derive a child HD public node, use deriveHdPublicNode on the result of this method. If the child uses a non-hardened index, it's also possible to use deriveHdPublicNodeChild.
