void calc_nonce	(	char *	_nonce,
		int	_expires,
		int	_index,
		str *	_secret
	)

Calculate nonce value.

Calculate nonce value value. The nonce value consists of the expires time (in seconds since 1.1 1970) and a secret phrase.

Parameters:

	_nonce	nonce value
	_expires	expires value
	_index	nonce index
	_secret	secret phrase

Calculate nonce value value. The nonce value consists of the expires time (in seconds since 1.1 1970) and a secret phrase.

Parameters:

	_nonce	nonce value
	_expires	expires value
	_index	nonce index
	_secret	secret

int check_nonce	(	str *	_nonce,
		str *	_secret
	)

Check nonce value received from user agent.

Parameters:

	_nonce	nonce value
	_secret	secret phrase

Returns:

0 when nonce is valid, -1 on errors, positive if nonce not valid
