2. [`PSA_KEY_DERIVATION_INPUT_SECRET`](https://mbed-tls.readthedocs.io/projects/api/en/development/api/group/group__derivation/#group__derivation_1ga0ddfbe764baba995c402b1b0ef59392e) for the password.
5. Call [`psa_key_derivation_output_bytes`](https://mbed-tls.readthedocs.io/projects/api/en/development/api/group/group__key__derivation/#group__key__derivation_1ga06b7eb34a2fa88965f68e3d023fa12b9) to obtain the output of the derivation. You may call this function more than once to retrieve the output in successive chunks.
Use [`psa_key_derivation_output_key`](https://mbed-tls.readthedocs.io/projects/api/en/development/api/group/group__key__derivation/#group__key__derivation_1gada7a6e17222ea9e7a6be6864a00316e1) instead if you want to use a chunk as a PSA key.
If you want to verify the output against an expected value (for authentication, rather than to derive key material), call `psa_key_derivation_verify_bytes` or `psa_key_derivation_verify_key` instead of `psa_key_derivation_output_bytes`.

The function `mbedtls_pkcs5_pbes2` is only intended as a support function to parse encrypted private keys in the PK module. It has no PSA equivalent.
