bendaali/NextBank-Core-Banking ? reverse-engineered prompt

Build me a complete banking app in C with a server, a command line client, and a small DLL API for outside apps to use.

I want the server to handle multiple clients at the same time, keep account and transaction data saved to files, and protect everything with password hashing, encryption, and basic integrity checks. The client should connect to localhost on port 8080 and let a user create an account, log in, deposit money, withdraw money, transfer money to another account, check balance, see account info, view history, and log out. Please also include admin commands for listing all accounts, making backups, showing logs, and searching by name.

It should validate inputs carefully, support simple reports, and be able to generate a PDF statement for an account. If needed, look up current docs online for any Windows socket or library details. Make it feel like a real working banking system, with clear messages, safe behavior, and clean code split into sensible source and header files.
