Hash Generator

Compute cryptographic hashes of text or files using the browser's native Web Crypto API. Generate SHA-1, SHA-256, SHA-384, and SHA-512 digests side by side as lowercase hex, and verify a file's integrity by comparing its checksum. Hashing runs locally, so even large files never leave your machine.

• SHA-1, SHA-256, SHA-384, and SHA-512 computed with the Web Crypto API
• Hash typed text or drag-and-drop files of any size
• Lowercase hex output for every algorithm at once for easy comparison
• Checksum verification - paste an expected hash to confirm a match
• UTF-8 encoding of text input for consistent, reproducible digests
• Streaming file reads so large files hash without freezing the page

1. 1

   Provide the input

   Type or paste text, or drop in a file. Text is encoded as UTF-8 before hashing so results are reproducible across tools.

2. 2

   Read the digests

   SHA-1, SHA-256, SHA-384, and SHA-512 hashes appear together as lowercase hex. Copy whichever one you need.

3. 3

   Verify a checksum (optional)

   Paste an expected hash to compare it against the computed value - the tool tells you whether they match.

• Verifying that a downloaded file matches its published checksum
• Generating content-addressable keys and cache identifiers
• Creating deterministic fingerprints for deduplication
• Producing digests for HMAC and webhook signature debugging
• Comparing two files or strings for byte-for-byte equality
