How to use the ssh-audit.SSH.Fingerprint function in ssh-audit

def output_fingerprint(kex, pkm, sha256=True, padlen=0):
	# type: (Optional[SSH2.Kex], Optional[SSH1.PublicKeyMessage], bool, int) -> None
	with OutputBuffer() as obuf:
		fps = []
		if pkm is not None:
			name = 'ssh-rsa1'
			fp = SSH.Fingerprint(pkm.host_key_fingerprint_data)
			bits = pkm.host_key_bits
			fps.append((name, fp, bits))
		for fpp in fps:
			name, fp, bits = fpp
			fpo = fp.sha256 if sha256 else fp.md5
			p = '' if out.batch else ' ' * (padlen - len(name))
			out.good('(fin) {0}{1} -- {2} {3}'.format(name, p, bits, fpo))
	if len(obuf) > 0:
		out.head('# fingerprints')
		obuf.flush()
		out.sep()
