static

This function returns a buffer given as a hex string.

The buffer is reversed so that the following are equivalent: mpi_fill_random( x, len, not_rnd, str ); mpi_read_string( x, 16, str ); (So, not random at all. Usefull to match test vectors.) Based on unhexify(), just reversed (changes marked by "sic")

static int rnd_buffer_rand ( void *  rng_state,
unsigned char *  output,
size_t  len 
)
static

This function returns random based on a buffer it receives.

rng_state shall be a pointer to a rnd_buf_info structure.

The number of bytes released from the buffer on each call to the random function is specified by per_call. (Can be between 1 and 4)

After the buffer is empty it will return rand();

static int rnd_pseudo_rand ( void *  rng_state,
unsigned char *  output,
size_t  len 
)
static

This function returns random based on a pseudo random function.

This means the results should be identical on all systems. Pseudo random is based on the XTEA encryption algorithm to generate pseudorandom.

rng_state shall be a pointer to a rnd_pseudo_info structure.

static int rnd_std_rand ( void *  rng_state,
unsigned char *  output,
size_t  len 
)
static

This function just returns data from rand().

Although predictable and often similar on multiple runs, this does not result in identical random on each run. So do not use this if the results of a test depend on the random data that is generated.

rng_state shall be NULL.
