This function reseeds the CTR_DRBG context, that is extracts data from the entropy source.

Syntax

int mbedtls_ctr_drbg_reseed( mbedtls_ctr_drbg_context *ctx,     const unsigned char *additional,     size_t len );
Implemented in ctr_drbg.c:379

Arguments

ctx

The CTR_DRBG context.

additional

Additional data to add to the state. Can be NULL.

len
