Hash Generator

Generate cryptographic hash digests for text using SHA-1, SHA-256, SHA-384, and SHA-512. Processing happens locally in your browser using the Web Crypto API.

Privacy & Security

All files are processed locally in your browser. Your data never leaves your device and is not uploaded to any server. We do not store, collect, or have access to your files.

How It Works

  1. 1

    Enter or paste the text you want to hash

  2. 2

    Choose a SHA algorithm

  3. 3

    The hash digest is generated automatically

  4. 4

    Copy the hexadecimal output for checksums, fixtures, or debugging

Use Cases

  • Create SHA-256 or SHA-512 digests for test fixtures

  • Compare text values without exposing raw content

  • Generate checksums for small text snippets

  • Debug API signing and hashing workflows

  • Create deterministic identifiers from text input

Frequently Asked Questions

Can this hash files?

This version hashes text input. File hashing can be added later as a separate workflow.

Is hashing done on the server?

No. The tool uses the browser Web Crypto API and does not upload your text.

Which algorithm should I use?

SHA-256 is a good default for most modern workflows. SHA-512 is also common. SHA-1 is included for legacy compatibility.

Can I reverse a hash?

No. Cryptographic hashes are one-way digests and cannot be decoded back into the original text.
