Functions

digest_fingerprint(fingerprint)

Calculate a cryptographic digest of the fingerprint.

Parameters:

fingerprint:  bytes – the fingerprint

Return value:

bytes – the digest

generate_key()

Generate a pair of cryptographic keys.

Return value:

ec.EllipticCurvePrivateKey – the keys

generate_mnemonic_key()

Generate a pair of cryptographic keys with a mnemonic for the private key.

Return value:

(str, ec.EllipticCurvePrivateKey) – the mnemonic and the keys

mnemonic_to_private_key(mnemonic)

Restore a private key from the given mnemonic.

Parameters:

mnemonic:  str – the mnemonic

Return value:
