SHA-256 is a cryptographic hash function that generates a 256-bit (32-byte) hash value. It is widely used to ensure data integrity and security by creating a unique digital fingerprint for a given input, making it highly resistant to tampering or duplication.

Secure Hash Algorithm 256-bit

SHA-256 (Secure Hash Algorithm 256-bit) is a widely used cryptographic hash function that belongs to the SHA-2 (Secure Hash Algorithm 2) family. It takes an input message of any length and produces a fixed-size 256-bit hash value.

Features

• The SHA-256 algorithm ensures the integrity and authenticity of the input message by generating a fixed-size hash value.
• SHA-256 offers a high level of collision resistance, making it highly improbable for two different messages to produce the same hash value.

Functionality

SHA-256 provides the following functionality:

• Given an input message, the tool calculates and displays the corresponding SHA-256 hash value.

Go Implementation

Run The main.go file Using Command:

go run main.go

Applications

SHA-256 is useful in so many circumstances! It’s a fast and secure hash function, here are some of the most common ways that it’s used:

• To create website authentication schemes, using JWTs, HMACs and MACs
• To create digital signatures
• To secure blockchains like Bitcoin and Ethereum
• In anti-viruses, to compare the fingerprints of files and programs
• In version control systems like Git to check if data has changed
