Hash Generator — MD5, SHA-256, SHA-512

Hash Generator tool

🔒 Runs in your browser · No uploads · Your data never leaves your device

How to use

1. 1

   Type or paste text

   Enter text in the input area. Hashes update automatically as you type.

2. 2

   Or select a file

   Drag and drop a file or tap to select one. The tool hashes the file contents locally in your browser.

3. 3

   Copy any hash

   Use Copy beside MD5, SHA-1, SHA-256, or SHA-512. Click Clear to reset all inputs and output.

Common use cases

• Verifying file integrity — Generate a SHA-256 hash of a downloaded file and compare it to the publisher's checksum to confirm the file hasn't been tampered with.
• Storing passwords safely — Understand how password hashing works by generating MD5 or SHA hashes and observing why salting is necessary.
• Creating cache keys — Hash request parameters or content to generate deterministic cache keys for API responses or build artifacts.
• Data fingerprinting — Generate a hash of a config file or dataset to detect changes between versions in a pipeline.

Examples

• Text hash

  Hash a short string instantly.

  Input

  hello

  Output

  MD5/SHA-1/SHA-256/SHA-512 are generated at once.

• File checksum

  Drop a file to verify integrity with SHA-256 or SHA-512.

  Output

  Use copied hashes for comparison.

Frequently asked questions

Is hashing done on the server?

No. All hashing runs entirely in your browser. Files and text are never uploaded.

Which algorithms are included?

MD5, SHA-1, SHA-256, and SHA-512 are generated simultaneously.

Can I hash files?

Yes. Use drag-and-drop or file picker to hash file contents directly in the browser.

Key concepts

Hash function

A one-way function that maps arbitrary data to a fixed-length output; the same input always produces the same hash.

MD5

A widely-used 128-bit hash algorithm — fast but cryptographically broken; suitable only for checksums, not security.

SHA-256

A 256-bit hash from the SHA-2 family; the current standard for cryptographic integrity verification.

Checksum

A hash value used to verify data integrity — comparing checksums confirms two files are identical.
