Functions
asciichat_error_t	ed25519_verify_signature (const uint8_t public_key[32], const uint8_t *message, size_t message_len, const uint8_t signature[64], const char *gpg_key_id)
	Verify an Ed25519 signature.
asciichat_error_t	ed25519_sign_message (const private_key_t *key, const uint8_t *message, size_t message_len, uint8_t signature[64])
	Sign a message with Ed25519 (uses SSH agent if available, otherwise in-memory key)
asciichat_error_t	parse_public_keys (const char *input, public_key_t *keys_out, size_t *num_keys, size_t max_keys)
	Parse all SSH/GPG public keys from any format (returns all keys)
asciichat_error_t	check_known_host (const char *server_ip, uint16_t port, const uint8_t server_key[32])
	Check if server key is in known_hosts.
asciichat_error_t	check_known_host_no_identity (const char *server_ip, uint16_t port)
	Check known_hosts for servers without identity key (no-identity entries)
bool	display_mitm_warning (const char *server_ip, uint16_t port, const uint8_t expected_key[32], const uint8_t received_key[32])
	Display MITM warning with key comparison and prompt user for confirmation.
bool	prompt_unknown_host (const char *server_ip, uint16_t port, const uint8_t server_key[32])
	Interactive prompt for unknown host - returns true if user wants to add, false to abort.
bool	prompt_unknown_host_no_identity (const char *server_ip, uint16_t port)
	Interactive prompt for unknown host without identity key - returns true if user wants to continue, false to abort.
asciichat_error_t	add_known_host (const char *server_ip, uint16_t port, const uint8_t server_key[32])
	Add server to known_hosts.
const char *	get_known_hosts_path (void)
asciichat_error_t	prompt_password (const char *prompt_text, char *password_out, size_t password_max_len)
	Prompt the user for a password with secure input.
