Cryptographic Hash Generator
Generate secure cryptographic hashes online. Compute SHA-1, SHA-256, SHA-384, SHA-512, and MD5 checksums client-side using the native Web Crypto API.
What is the Hash Generator?
The Hash Generator computes fixed-length cryptographic checksums from any plain text input across multiple standard hashing algorithms simultaneously.
How to Use the Tool
- Enter or paste your text string into the input editor.
- View live computed hashes for SHA-1, SHA-256, SHA-384, SHA-512, and MD5.
- Click the copy icon next to any specific algorithm to grab the hash.
Common Use Cases
- Verifying file integrity and data checksums.
- Validating password and secret token hashing algorithms.
- Generating cache keys and deterministic unique fingerprints.
Supported Formats & Options
Supports SHA-1, SHA-256, SHA-384, SHA-512 (via window.crypto.subtle), and MD5. Includes uppercase/lowercase hex toggles and live generation.

Frequently Asked Questions
Is my input string or secret logged?
No. Hashes are computed 100% locally in your browser using the native Web Crypto API. No data is sent over the network.
Which hashing algorithm is recommended for security?
SHA-256 and SHA-512 are industry standards for data integrity and cryptographic verification. MD5 and SHA-1 should only be used for legacy checksums.
