* #PSA_KEY_DERIVATION_INPUT_SECRET is the shared secret K from EC J-PAKE.
* The only supported curve is secp256r1 (the 256-bit curve in
* #PSA_ECC_FAMILY_SECP_R1), so the input must be exactly 65 bytes.
* The output has to be read as a single chunk of 32 bytes, defined as
* PSA_TLS12_ECJPAKE_TO_PMS_DATA_SIZE.
