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.

both used record.copy() (shallow), leaving unencrypted mutable fields shared between the input and the returned dict, violating the documented 'input is not mutated' contract. switched to copy.deepcopy.
