[Secure Enclave] Implement PKI parsing support in Solidity

[dineshpinto]

• Description:
  Design and implement support for Confidential Space PKI key parsing in Solidity within flare-vtpm-attestation
• Acceptance Criteria:
  • In-contract PKI key parsing and validation support (see Google docs for example PKI key parsing)
  • Similar functionality and interface to existing OIDC parser in FlareVtpmAttestation.sol
• Key Files/Modules Involved (Tentative):
  • flare_vtpm_attestation/contracts/verifiers/PKIValidator.sol
• Tasks / Implementation Steps:
  • See the example implementation of OIDC key verification
  • Based on this develop a similar interface for PKI key verification, add additional files under contracts/types/ and contracts/utils/ as needed
  • Set up unit tests similar to FlareVtpmAttestation.t.sol
  • An example PKI key for testing can be found in pki.txt

Hello, can i takke on Issue #40: Implement PKI parsing support in Solidity within the flare-ai-kit project.

I have strong foundation in smart contract development and experience working with Solidity, I’ve reviewed the relevant components such as PKIValidator.sol and understand the value of unit testing, type definitions, and utility abstractions in Solidity. I’m confident I can deliver a robust and secure implementation based on the acceptance criteria.

I can finish in 30hours
