Applied Cryptography | Security Engineering | Cybersecurity
I'm a Computer Science student building toward applied cryptography and secure systems engineering — exploring secure communication protocols, key management, PKI, and TLS, with a goal of moving into cryptography research and security engineering.
About Me
I'm Shubham Mishra, a B.Tech Computer Science (Cyber Security) student at VIT, currently maintaining a CGPA of 9.01/10. My work centers on applied cryptography — building and reasoning about systems that rely on AES, RSA, ChaCha20, and modern authenticated encryption schemes.
I'm particularly interested in secure communication protocols, public key infrastructure (PKI), and TLS, and I enjoy working close to the system: Linux internals, key management, and the engineering decisions that make cryptographic systems trustworthy in practice.
Longer term, I'm working toward research and engineering roles in cryptography and secure systems — through graduate study or applied cryptography engineering positions — with a focus on building primitives and protocols that hold up under real-world scrutiny.
Experience
- Engineered an automated conformance testing framework for ETSI GS QKD 014 Key Management Entity (KME) APIs using Python and FastAPI.
- Implemented secure HTTPS and Mutual TLS (mTLS) communication to validate cryptographic key management endpoints against protocol specifications.
- Automated test execution, HTML report generation, and Excel test plan creation, improving the efficiency and reproducibility of cryptographic compliance testing.
