Function Documentation

void _otp_pthread_mutex_init	(	pthread_mutex_t *	mutexp,
		pthread_mutexattr_t const *	attr,
		char const *	caller
	)

Guaranteed initialization.

Definition at line 82 of file otp_util.c.

Here is the call graph for this function:

void _otp_pthread_mutex_lock	(	pthread_mutex_t *	mutexp,
		char const *	caller
	)

Guaranteed lock.

Definition at line 98 of file otp_util.c.

Here is the call graph for this function:

int _otp_pthread_mutex_trylock	(	pthread_mutex_t *	mutexp,
		char const *	caller
	)

	)

void otp_async_challenge	(	char	challenge[OTP_MAX_CHALLENGE_LEN+1],
		size_t	len
	)

Generate a random challenge (ascii chars 0-9)

Note

This is really cryptocard-specific (automatic ASCII conversion

and null termination).

Parameters

[out]	challenge	Buffer to write random string to.
[in]	len	Number of random bytes to write to buffer.

Definition at line 63 of file otp_util.c.

Here is the call graph for this function:

Here is the caller graph for this function:

size_t otp_gen_state	(	char	state[OTP_MAX_RADSTATE_LEN],
		char const	challenge[OTP_MAX_CHALLENGE_LEN],
		size_t	clen,
		int32_t	flags,
		int32_t	when,
		uint8_t const	key[16]
	)

Generate an OTP state value.

Generates an OTP state value (an string of ASCII hexits in an opaque binary string).

Parameters

[out]	state	buffer in which to write the generated state value.
[in]	challenge	The challenge value.
[in]	clen	The length of the challenge data.
[in]	flags	to remember.
[in]	when	the challenge was originally generated.
[in]	key	HMAC key.

Returns

the amount of data written into the state buffer.
