Developed ML-DSA key and certificate support for the aws/rolesanywhere-credential-helper repository, enabling compatibility with ML-DSA-44, ML-DSA-65, and ML-DSA-87 key types. The work involved updating the Go-based signing logic and automating key generation and certificate handling through enhancements to the Makefile. Unit tests were added to validate the new cryptographic flows, ensuring robust verification and maintaining backward compatibility. By expanding cryptographic support and automating workflows, the project improved security posture and reduced operational risk. The technical approach emphasized Go programming, cryptography, and unit testing, resulting in a focused, well-tested feature that enhances the repository’s flexibility and reliability.
