scramble()

void scramble	(	char *	to,
		const char *	message,
		const char *	password
	)

Produce an obscure octet sequence from password and random string, received from the server.

This sequence corresponds to the password, but password can not be easily restored from it. The sequence is then sent to the server for validation. Trailing zero is not stored in the buf as it is not needed. This function is used by client to create authenticated reply to the server's greeting.

Parameters

[out]	to	store scrambled string here. The buf must be at least SHA1_HASH_SIZE bytes long.
	message	random message, must be exactly SCRAMBLE_LENGTH long and NULL-terminated.
	password	users' password, NULL-terminated
