Hash Generator

Generate SHA-256, SHA-384, SHA-512 hashes.

About this tool

This tool generates SHA-256/384/512 hashes in one click. Three features: 1) Supports three hash algorithms, 2) All processing in browser—no data sent to server, 3) Useful for password hashing, file integrity, API signature verification.

Tool interface

Auto-computes on input

SHA-256
SHA-384
SHA-512

Usage

  1. Enter text in the input field
  2. SHA-256, SHA-384, SHA-512 hashes are generated automatically
  3. Copy generated hash for password, integrity check, or signature verification

When to use

Verifying password hash design, file checksum comparison, API signature verification.

Examples

password123 → SHA-256: 6ca13d52..., file hash for tampering detection.

FAQ

What is SHA-256?

Secure Hash Algorithm 256. One-way function producing 256-bit (64 hex char) hash. Same input → same hash.

Hash vs encryption?

Encryption is reversible. Hash is one-way. Use hash for passwords, encryption for secrecy.

Why hash passwords?

Plain text is risky if leaked. Hash is irreversible; verify by hashing input and comparing. Prefer bcrypt/Argon2 for passwords.

SHA-256 vs SHA-512?

Different output length: 256 vs 512 bits. Both secure; SHA-512 slightly stronger, longer output.

Is Hash Generator free?

Free to use, no sign-up required.

Is data sent to a server?

Data stays on your device; we do not store it on our servers.

Supported browsers?

Tested on recent Chrome, Edge, Firefox, and Safari.

Offline use?

Core features work offline after the first load.

vs CLI or desktop apps?

Hash Generator is an install-free online alternative to CLI or desktop apps.

When to use it?

Use it when: Verifying password hash design, file checksum comparison, API signature verification.

Usage example?

Example: password123 → SHA-256: 6ca13d52..., file hash for tampering detection.

Main features?

SHA-256/384/512 support, Browser-only processing, Password and integrity check

How is this different from similar tools?

Hash Generator runs in the browser with no install—ideal for quick checks before heavier CLI or IDE workflows.
