NAME

6       kcapi_rng_seed - seed the RNG
7

SYNOPSIS

9       int kcapi_rng_seed(struct kcapi_handle * handle, uint8_t * seed,
10                          uint32_t seedlen);
11

ARGUMENTS

13       handle
14           [in] cipher handle
15
16       seed
17           [in] seed data
18
19       seedlen
20           [in] size of seed
21

DESCRIPTION

23       Note, this call must be called to initialize the selected RNG. When the
24       SP800-90A DRBG is used, this call causes the DRBG to seed itself from
25       the internal noise sources.
26
27       Note, in case of using the SP800-90A DRBG, the seed buffer may be NULL.
28       If it is not NULL, the DRBG uses the given data either as
29       personalization string in case of the initial seeding or additional
30       data for reseeding.
31
32       return 0 upon success; a negative errno-style error code if an error
33       occurred
