SHA-512 Hash Generator

Summary

This tool computes a SHA-512 cryptographic hash of any text you enter, entirely inside your browser using the native WebCrypto API. No data leaves your device. SHA-512 produces a 128-character hexadecimal digest and is widely used for verifying data integrity and storing password hashes securely.

How it works

1. Type or paste your text into the input field.
2. The tool calls the browser's built-in WebCrypto SubtleCrypto.digest() method.
3. The resulting 64-byte ArrayBuffer is converted to a hex string.
4. Toggle the case switch to display the hash in uppercase or lowercase.
5. Click "Copy Hash" to copy the result to your clipboard.

Use cases

• Verify file or message integrity by comparing SHA-512 checksums.
• Generate hash values during development and testing.
• Check whether two pieces of text produce the same hash.
• Learn how SHA-512 output changes with even a single character difference.
• Quickly produce a hash without installing any local tools.
• Validate server-generated hashes against a trusted client-side reference.
