Stokade Website

A website for managing stock in a coffee shop. I’m using C#, ASP.NET, and a local SQL database. So far, I’ve implemented a login page and three pages for different types of stock. The goal is to continue developing this into a full business solution to simplify stock management.

SHA-256 (Secure Hash Algorithm 256-bit) is a cryptographic hash function that takes any input data and transforms it into a unique, fixed-size 256-bit (32-byte) hash value, typically represented as a 64-character hexadecimal string. Implemented using C#.
