mbedtls_ctr_drbg_seed() function

This function seeds and sets up the CTR_DRBG entropy source for future reseeds.

Syntax

int mbedtls_ctr_drbg_seed( mbedtls_ctr_drbg_context *ctx, int (*f_entropy)(void *, unsigned char *, size_t), void *p_entropy, const unsigned char *custom, size_t len );

Implemented in ctr_drbg.c:117

The CTR_DRBG context to seed.

The entropy callback, taking as arguments the \p p_entropy context, the buffer to fill, and the length of the buffer.

The entropy context.

Personalization data, that is device-specific identifiers. Can be NULL.

The length of the personalization data.

\c 0 on success. #MBEDTLS_ERR_CTR_DRBG_ENTROPY_SOURCE_FAILED on failure.

Personalization data can be provided in addition to the more generic entropy source, to make this instantiation as unique as possible.
