|
|
Your function must be called
|
|
mbedtls_hardware_poll(), have the same prototype
|
|
as declared in entropy_poll.h, and accept NULL as
|
|
first argument.

bool "Disable the built-in platform entropy functions"

help
|
|
Do not use built-in platform entropy functions.
|
|
This is useful if your platform does not support
|
|
standards like the /dev/urandom or Windows
|
|
CryptoAPI.

depends on MBEDTLS_SHA256_C
|
|
help
|
|
Force the entropy accumulator to use a SHA-256
|
|
accumulator instead of the default SHA-512 based
|
|
one (if both are available). On 32-bit systems SHA-256
|
|
can be much faster than SHA-512. Use this option if you
|
|
have performance concerns.
