This pull request introduces a new feature for supporting request signatures in the
Forwardmodule of the Checkout SDK. It adds the ability to configure and generate signatures, specifically for the dLocal API, by extending theDestinationRequestclass and introducing new classes and enums for signature handling.Enhancements to request signature support:
DestinationRequestclass update: Added an optionalSignatureproperty of typeAbstractSignatureto allow configuration of request signatures. (src/CheckoutSdk/Forward/Requests/DestinationRequest.cs, src/CheckoutSdk/Forward/Requests/DestinationRequest.csR22-R26)AbstractSignatureclass: Introduced an abstract class to define the base structure for signature generation, including aTypeproperty for specifying the signature type. (src/CheckoutSdk/Forward/Requests/Signatures/AbstractSignature.cs, src/CheckoutSdk/Forward/Requests/Signatures/AbstractSignature.csR1-R13)dLocal-specific signature implementation:
DlocalParametersclass: Added a class to encapsulate the required parameters, such as theSecretKey, for generating dLocal API signatures. (src/CheckoutSdk/Forward/Requests/Signatures/DlocalParameters.cs, src/CheckoutSdk/Forward/Requests/Signatures/DlocalParameters.csR1-R10)DlocalSignatureclass: Created a class to handle dLocal-specific signature generation, including appending headers likeX-DateandAuthorizationto outgoing requests. (src/CheckoutSdk/Forward/Requests/Signatures/DlocalSignature.cs, src/CheckoutSdk/Forward/Requests/Signatures/DlocalSignature.csR1-R14)SignatureTypeenum: Added an enum to define supported signature types, starting withDlocal. (src/CheckoutSdk/Forward/Requests/Signatures/SignatureType.cs, src/CheckoutSdk/Forward/Requests/Signatures/SignatureType.csR1-R10)
