@ -458,9 +458,7 @@ For `PSA_ALG_JPAKE` the following steps are available for input operation:
* `PSA_JPAKE_X4S_STEP_ZK_PUBLIC`    Round 2: input Schnorr NIZKP public key for the X4S key
* `PSA_JPAKE_X4S_STEP_ZK_PROOF`     Round 2: input Schnorr NIZKP proof for the X4S key
The core has checked that input_length is smaller than PSA_PAKE_INPUT_SIZE(PSA_ALG_JPAKE, primitive, step)
where primitive is the JPAKE algorithm primitive and step the PSA API level input step.
Thus no risk of integer overflow while checking operation buffer overflow.
The core checks that input_length is smaller than PSA_PAKE_INPUT_MAX_SIZE.
