During October 2024, McCleeary enhanced cryptographic validation pipelines in the GaloisInc/ckzg-eip-4844-verification repository by developing a blob validation utility for BLS modulus compliance and expanding KZG proof verification test vectors. Using Python and Cryptol, McCleeary implemented a generator that converts blobs to field elements, applies the modulus, and reconstructs valid blobs, increasing test coverage and reliability for EIP-4844. In GaloisInc/cryptol-specs, McCleeary removed outdated SphincsPlus code and updated documentation, improving onboarding and module usability. The work demonstrated depth in cryptographic implementation, code maintenance, and cross-repository test alignment, resulting in more robust and maintainable cryptographic modules.
