Hash Generator

Create cryptographic hashes from text or whole files, right in your browser. Supports MD5, SHA-1 and the SHA-2 family.

Enter text to hash:

Result:

Hash a file

Select a file to hash its exact bytes. Works with SHA algorithms; MD5 is applied to the decoded UTF-8 text.

How to generate a hash

Type or paste the text you want to hash, or select a file instead.
Pick an algorithm: MD5, SHA-1, SHA-256, SHA-384 or SHA-512.
Click Generate Hash (or select a file) to compute it.
Copy the lowercase hex digest for verification or storage.

FAQs

What is a hash?

A hash is a fixed-length string produced from arbitrary data. The same input always yields the same hash, and even a tiny change produces a completely different one.

Which algorithm should I use?

For most uses, SHA-256 is a solid default. MD5 and SHA-1 are fast but considered cryptographically weak, so avoid them for security-sensitive checks.

Can I hash a whole file?

Yes. Use the file option to hash the raw bytes of a file. SHA hashes use the file bytes directly, while MD5 decodes them as UTF-8 text first.

Does the tool upload my data?

No. Hashing runs entirely in your browser. Your text and files never leave your device.

Why generate hashes?

A hash is a fixed-length fingerprint of any text or file, so you can verify integrity, deduplicate data or compare values without storing the original. The same input always produces the same hash.

Verify file integrity by comparing SHA-256 checksums after download.
Detect accidental data changes during transfer or storage.
Produce a quick non-reversible identifier for caching or dedup.

Tips and Limits

MD5 and SHA-1 are fine for checksums but not cryptographically secure for passwords — prefer SHA-256, SHA-384 or SHA-512, which use the browser's WebCrypto. Hashing runs entirely locally.
