How to Use Hash Generator

Our Hash Generator is a free cryptographic utility: 1. Type or paste text into the input box. 2. All four hashes (MD5, SHA-1, SHA-256, SHA-512) update in real time. 3. Click 'Copy' next to any hash to copy it to your clipboard. 4. To hash a file, drag and drop it into the file area or click the file picker.

Hash Generator Formula / How It Works

MD5 hashes are computed using the battle-tested blueimp-md5 library. SHA-1, SHA-256, and SHA-512 use the browser's native WebCrypto API (window.crypto.subtle.digest). All computations run locally in your browser.

Formula:MD5 uses the blueimp-md5 library. SHA-1, SHA-256, and SHA-512 use the browser's native WebCrypto API: window.crypto.subtle.digest().
Example Calculation:

For example, hashing the string 'hello' produces: MD5: 5d41402abc4b2a76b9719d911017c592 | SHA-256: 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824

Frequently Asked Questions

A hash is a fixed-length string generated from any input using a one-way mathematical function. Hashes are used to verify file integrity, store passwords securely, and create digital signatures.

For security-sensitive applications like password storage or digital signatures, use SHA-256 or SHA-512. MD5 and SHA-1 are considered cryptographically weak and should only be used for checksums and file integrity verification, not for security.

Yes! Use the file picker or drag and drop a file into the file hash area. Files are processed locally in your browser and never uploaded to a server. Maximum supported file size is 500MB.

Yes. Hash functions are deterministic — the same input always produces the same output. Even a single character difference in the input produces a completely different hash.
