 # Golang Backend API using Echo for FSI(File System Integrity) Application
-Developing a simple Golang backend API using the [Echo framework](https://github.com/labstack/echo). This API stores IDs and their corresponding hashes in a SQL server and provides functionality to verify if a given hash matches the stored hash for a specific ID, thereby providing integrity service that aligns with the CIA (Confidentiality, Integrity, Availability) triad for data security.

This API stores IDs and their corresponding hashes in a SQL server and provides functionality to verify if a given hash matches the stored hash for a specific ID. All the communication between the Application and API will secured using TLS encryption(HTTPS).

 - To add a file hash, make a POST request to `/add` with JSON data containing the ID and hash.
 - To verify a file hash, make a POST request to `/verify` with JSON data containing the ID and hash.

+- [ ] Perform Hashing (API/Application)
+- [ ] Connect with DB
