What is a SHA-256 Hash Generator?

A SHA-256 Hash Generator is a tool that uses the Secure Hash Algorithm 256-bit to convert any text into a fixed-size, 64-character hexadecimal string. SHA-256 is a cryptographic hash function designed by the NSA and is a standard for modern data security. It's a one-way function, meaning it's easy to create the hash but computationally infeasible to reverse it.

What Problem Does This Tool Solve?

SHA-256 is fundamental to modern security. It's used in digital signatures, password protection, and most famously, in blockchain technology like Bitcoin. Developers and security professionals often need to quickly generate a SHA-256 hash to verify data, test an implementation, or create a checksum. This tool provides a simple, accessible way to do that without needing to write code or use a command-line interface.

Frequently Asked Questions (FAQ)

1. What's the difference between MD5 and SHA-256?

SHA-256 is significantly more secure than MD5. It produces a longer hash (256 bits vs. 128 bits) and has no known collision attacks, making it the preferred choice for security-sensitive applications.

2. Will "Hello" and "hello" produce the same hash?

No. Hashing is case-sensitive. Even a tiny change in the input text will produce a completely different hash.

3. Is my data private?

Yes. All hashing is performed securely in your browser. Your input text is never sent to our servers.
