Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes online. All hashing runs locally in your browser.
How to Use
- Type or paste any text into the input field — hashes are computed in real time as you type.
- All four hash values (MD5, SHA-1, SHA-256, SHA-512) update automatically.
- Click the Copy button next to any hash to copy it to your clipboard.
Frequently Asked Questions
- Are these hashes secure for storing passwords?
- No. MD5 and SHA-1 are cryptographically broken for security purposes. SHA-256/SHA-512 are stronger, but for passwords you should use dedicated algorithms like bcrypt, scrypt, or Argon2.
- Is MD5 supported via Web Crypto API?
- Web Crypto API does not support MD5. This tool computes MD5 using a pure JavaScript implementation built directly into the page.
- Are my inputs sent to any server?
- No. All hashing is performed entirely in your browser. Nothing is transmitted over the network.
- What is the difference between SHA-256 and SHA-512?
- Both are part of the SHA-2 family. SHA-256 produces a 256-bit (64 hex char) digest, SHA-512 produces a 512-bit (128 hex char) digest. SHA-512 is slower but has a larger output space.
