Hi @vindicatorr, mbedtls_pkcs5_pbkdf2_hmac is not deprecated in idf v4.4.3 and v5.0. Thats why esp32 using mbedtls_pkcs5_pbkdf2_hmac. mbedtls_pkcs5_pbkdf2_hmac_ext will be supported in upcoming release

That's why I mentioned I was using the Master branch for everything, and it's just a heads-up for what's coming down the pipeline.
