Cryptographic signature calculation is based on the string of parameters in exactly the same order as listed in the specification (see above).

maskClnRP|20220125131601|****0209|11/16|415461****0209

Note: Signature of the core parameters remains unchanged. The extensions item does not affect the calculation of the payment/status response. Each extension has its own signature.

Extension signature and its validation uses the same algorithm SHA1withRSA (for API 1.7 and older) or SHA256withRSA (for API 1.8 and newer).
