A hash is a fixed-length fingerprint of data produced by a one-way function. Same input yields the same digest; small changes produce very different outputs.

How do I generate a SHA-256 hash?

Enter your text above and copy the SHA-256 row. Generation happens instantly in your browser.

What is the difference between MD5 and SHA-256?

MD5 is older, shorter, and cryptographically broken for collision resistance. SHA-256 is a modern SHA-2 digest widely used for integrity. Prefer SHA-256 or stronger for security use cases.

Can a hash be reversed?

No practical reversal exists for strong hashes. Attackers instead guess inputs or use precomputed tables. That is why passwords need slow keyed hashing, not raw SHA-256 alone.

Which hashing algorithm should I use?

For general integrity checks, use SHA-256 or SHA-512. Avoid MD5 and SHA-1 for security-sensitive designs; they remain here mainly for legacy comparison and learning.

What is Hash Generator?

A free online tool that creates cryptographic digests from text for students and practitioners.

How does the Hash Generator work?

It encodes your text as UTF-8 and runs MD5 plus SHA-1/2 algorithms locally, then displays hex digests you can copy.

How do I use the Hash Generator?

Type text, optionally tap an example chip, and copy the digest you need from the result list.

Is this Hash Generator free to use?

Yes. It is free with no sign-up.

Can I use the Hash Generator on mobile?

Yes. It works in mobile browsers that support Web Crypto.
