Free Hash Calculator - MD5, SHA-1, SHA-256, SHA-512 | ToolZen
Calculate MD5, SHA-1, SHA-256, and SHA-512 hashes using Web Crypto API. 100% client-side.
Frequently Asked Questions
1. What hashing algorithms are supported?
Our hash calculator supports MD5, SHA-1, SHA-256, and SHA-512. These are computed using the browser's native Web Crypto API for security and performance.
2. Is the hashing done securely?
Yes. All hashing is performed locally in your browser using the Web Crypto API. Your data is never transmitted to any server.
3. Can I verify file hashes?
Yes! You can drag and drop any file (ISO images, installers, archives, etc.) into the file hash zone below to calculate its MD5, SHA-1, SHA-256, and SHA-512 hashes. Your file never leaves your browser.
