+ * template:  src/crypto/tls_none.c
+ * reference: src/crypto/tls_*.c
+ *
+ * Known Limitations:
+ * - no TLSv1.3 (not available in mbedtls 2.x; experimental in mbedtls 3.x)
+ * - no OCSP (not yet available in mbedtls)
+ * - mbedtls does not support all certificate encodings used by hwsim tests
+ *   PCKS#5 v1.5
+ *   PCKS#12
+ *   DH DSA
+ * - EAP-FAST, EAP-TEAP session ticket support not implemented in tls_mbedtls.c
+ * - mbedtls does not currently provide way to set an attribute in a CSR
+ *     https://github.com/Mbed-TLS/mbedtls/issues/4886
+ *   so tests/hwsim dpp_enterprise tests fail
+ * - DPP2 not supported
+ *   PKCS#7 parsing is not supported in mbedtls
+ *   See crypto_mbedtls.c:crypto_pkcs7_get_certificates() comments
+ * - DPP3 not supported
+ *   hpke_base_seal() and hpke_base_seal() not implemented in crypto_mbedtls.c
+ *
+ * Status:
+ * - code written to be compatible with mbedtls 2.x and mbedtls 3.x
+ *   (currently requires mbedtls >= 2.27.0 for mbedtls_mpi_random())
+ *   (currently requires mbedtls >= 2.18.0 for mbedtls_ssl_tls_prf())
+ * - builds with tests/build/build-wpa_supplicant-mbedtls.config
+ * - passes all tests/ crypto module tests (incomplete coverage)
+ *   ($ cd tests; make clean; make -j 4 run-tests CONFIG_TLS=mbedtls)
+ * - passes almost all tests/hwsim tests
+ *   (hwsim tests skipped for missing features)
+ *
+ * RFE:
+ * - EAP-FAST, EAP-TEAP session ticket support not implemented in tls_mbedtls.c
+ * - client/server session resumption, and/or save client session ticket
