Function: eventsUploadEncodeHashVerify(EventTypes.EventUpload data, address signer)

Allows verification of an event upload payload.

Inputs

• data

  • Control: Fully controlled by the calling function.

  • Constraints: Needs to be part of a valid signature.

  • Impact: The data struct that contains the signed message and its signature.

• signer

  • Control: Fully controlled by the calling function.

  • Constraints: Returns whether it matches the recovered signature's signer.

  • Impact: Presumably the signer of the message.

Branches and code coverage

Intended branches

• Assure that signature is not replayable. Currently not enforced as no nonce is used.

  Test coverage

• Assure that the timestamp of signature is not in the past. Currently not enforced, as there is no timestamp.

  Test coverage

• Return whether the signer matches the recovered's address.

  Test coverage

• Assure that signature is not malleable. Currently enforced as ECDSA is used.

  Test coverage

Negative behavior

• Should not exclude any of the data from the hash. Currently not enforced at this function level.
