Hash Generator

Generate SHA1, SHA256, SHA384, SHA512 cryptographic hashes with file support, HMAC, verification, and batch processing.

Algorithms:

Enter text and select an algorithm to generate hashes.

The Hash Generator creates cryptographic hashes — SHA-1, SHA-256, SHA-384, and SHA-512 — from text or files, with optional HMAC. Enter your input and get the hash instantly for checksums, verification, and integrity checks.

How to generate a hash

  1. Enter text or select a file.
  2. Choose the hash algorithm (for example SHA-256).
  3. Copy the generated hash, or compare it against an expected value to verify integrity.

What is a hash used for?

A hash is a fixed-length fingerprint of data. Identical input always produces the same hash, so hashes are used to verify downloads, store password checks, and detect whether data has changed.

Frequently Asked Questions

What is the difference between SHA-256 and SHA-512?

Both are secure SHA-2 hashes; SHA-512 produces a longer 512-bit digest and is often faster on 64-bit systems, while SHA-256 produces a 256-bit digest. Choose based on your requirement.

Can a hash be reversed?

No. Cryptographic hashes are one-way — you cannot recover the original input from the hash.

What is HMAC?

HMAC combines a secret key with the hash to authenticate a message, proving it came from someone who knows the key.

Is the hash generator secure and private?

Yes. Hashing runs entirely in your browser, so your text or files are never uploaded.
