@ -4,6 +4,8 @@ Remove the option to build the library without any entropy sources
This does not affect users who use the default `config.h`, as this option was
already off by default.
If you were using the `MBEDTLS_TEST_NULL_ENTROPY` option, you can either use
`MBEDTLS_ENTROPY_NV_SEED` or create a fake entropy function.
If you were using the `MBEDTLS_TEST_NULL_ENTROPY` option and your platform
doesn't have any entropy source, you should use `MBEDTLS_ENTROPY_NV_SEED`
and make sure your device is provisioned with a strong random seed.
Alternatively, for testing purposes only, you can create and register a fake
entropy function.
