Function Documentation

◆ mbedtls_hardclock_poll()

int mbedtls_hardclock_poll ( void *  data,
unsigned char *  output,
size_t  len,
size_t *  olen 
)

mbedtls_timing_hardclock-based entropy poll callback

◆ mbedtls_havege_poll()

int mbedtls_havege_poll ( void *  data,
unsigned char *  output,
size_t  len,
size_t *  olen 
)

HAVEGE based entropy poll callback.

Requires an HAVEGE state as its data pointer.

int mbedtls_platform_entropy_poll ( void *  data,
unsigned char *  output,
size_t  len,
size_t *  olen 
)

Entropy poll callback that provides 0 entropy.
