SHA-256 Learning Implementation

This repository contains a simple implementation of SHA-256, created for learning purposes only.
⚠️ It is not intended for production use.

---

Running the Example Solutions

To view the answers for the tasks from the assignment sheet, run:

go run main.go

Alternatively, you can check the hash_test.go file, which also contains tests related to the exercises.

---

Running the SHA-256 Function

To compute a SHA-256 hash for a custom message, run:

go run cmd/main.go hash <your-message>

Arguments

Argument	Description
<your-message>	Message to be hashed. Example: "hello world"

This will print logs to help you follow and understand the process.

---

Running with Weak Hashing (for experimentation)

You can also try a weaker version of the SHA-256 function with additional parameters:

go run cmd/main.go hash <your-message> <iterations> false

Arguments

Argument	Description
<your-message>	Message to be hashed. Example: "hello world"
<iterations>	Number of loops (iterations) – defines how many times the hashing process is repeated.
false	Uses a weaker version of the hash function – useful for experimentation and learning.

This allows you to experiment with reduced hashing strength for learning purposes.
