/**
* \def MBEDTLS_USE_PSA_CRYPTO
*
* Make the X.509 and TLS library use PSA for cryptographic operations, and
* enable new APIs for using keys handled by PSA Crypto.
* Make the X.509 and TLS libraries use PSA for cryptographic operations as
* much as possible, and enable new APIs for using keys handled by PSA Crypto.
*
* \note Development of this option is currently in progress, and parts of Mbed
* TLS's X.509 and TLS modules are not ported to PSA yet. However, these parts
* will still continue to work as usual, so enabling this option should not
* break backwards compatibility.
*
* \note See docs/use-psa-crypto.md for a complete description of what this
* option currently does, and of parts that are not affected by it so far.
*
* \warning If you enable this option, you need to call `psa_crypto_init()`
* before calling any function from the SSL/TLS, X.509 or PK modules.
*
* \note Even with this option disabled, some code in PK, X.509, TLS or the
* crypto library might still use PSA drivers, if it can determine it's safe
* to do so.
*
* \note See docs/use-psa-crypto.md for a complete description this option.
*
* Requires: MBEDTLS_PSA_CRYPTO_C.
*
* Uncomment this to enable internal use of PSA Crypto and new associated APIs.
