Two C programs for nurses and consultants to securely store and retrieve patient records with simple Caesar-cipher encryption
Two C programs that let a nurse create encrypted patient records and a consultant retrieve/update them, using Caesar cipher for 'encryption'. This is a CS student project demonstrating file I/O and basic program structure, not anything you'd put near real patient data.
Cleanly scoped into two separate programs with a clear role boundary. Compiles with standard C11 and no exotic dependencies. The README is honest that this is a learning exercise and explicitly calls out Caesar cipher as the encryption mechanism. The author even lists the obvious next steps (AES, SQLite) without pretending the current state is production-ready.
Caesar cipher is not encryption — it's a toy substitution that any grep of the binary or hex dump defeats instantly. Storing credentials as Caesar-ciphered text in a file means anyone with filesystem read access owns all records. No Makefile means build instructions are manual copy-paste. The 'authentication' model is a single hardcoded username/password pair per role, which means all nurses share one account — no audit trail of who accessed what, which is the thing that actually matters in healthcare.
