get_rsa_key_fingerprint(is_private=True) only loaded PEM private keys, so an OpenSSH-format private key raised — unlike decrypt_aes_key_with_rsa, which already had the fallback. mirrored it: on a PEM load failure, an OPENSSH-marked key is loaded via load_ssh_private_key. also normalized the encrypted-key-without-password case: cryptography raises TypeError there, which now becomes a clear ValueError('private key is encrypted but no password was provided') in both methods instead of leaking the raw TypeError.

get_rsa_key_fingerprint(is_private=True) called load_pem_private_key(password=None),
so an encrypted private key raised a raw TypeError. add an optional password param
forwarded to the load; unencrypted keys ignore it.
verified: encrypted private key fingerprints with its password and matches the
public key's fingerprint; missing password still raises.
