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

seed

seedlen

Note, this call must be called to initialize the selected RNG​. When the SP800-90A DRBG is used, this call causes the DRBG to seed itself from the internal noise sources​.

Note, in case of using the SP800-90A DRBG, the seed buffer may be NULL​. If it is not NULL, the DRBG uses the given data either as personalization string in case of the initial seeding or additional data for reseeding​.

return 0 upon success; a negative errno-style error code if an error occurred
