# When using Mbed Crypto's PSA Entropy Injection feature on Mbed OS, it is
|
|
# not required to opt out of having entropy sources added to your entropy
|
|
# contexts by default (via MBEDTLS_NO_DEFAULT_ENTROPY_SOURCES).
|
|
# As integrated in Mbed OS, MBEDTLS_PSA_INJECT_ENTROPY is compatible with
|
|
# actual entropy sources. PSA entropy injection is implemented using the
|
|
# standard Mbed TLS NV Seed feature, and is as compatible with other
|
|
# entropy sources as the standard Mbed TLS NV Seed feature which does
|
|
# support entropy mixing.
