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

This tool supports MD5, SHA-1, SHA-256, SHA-384, and SHA-512. For security-sensitive use cases, SHA-256 or SHA-512 are recommended; MD5 and SHA-1 are considered cryptographically weak and should not be used for passwords or security-critical applications.

Yes. Paste the content of a file (or the file name/path as text) and compare the generated hash to an expected checksum. This is commonly used to verify downloaded software packages have not been tampered with.

No. MD5, SHA-1, and even SHA-256 alone are not suitable for hashing passwords because they are too fast — attackers can compute billions of hashes per second. Use bcrypt, Argon2, or scrypt (with salting and key stretching) for password storage.

No. All hashing is performed entirely in your browser using the Web Crypto API (SHA family) or a local MD5 implementation. Your text input is never transmitted to any external server.

MD5 produces a 128-bit (32 hex character) hash and is fast but cryptographically broken. SHA-1 produces a 160-bit (40 hex character) hash and is also deprecated for security use. SHA-256 produces a 256-bit (64 hex character) hash and is currently secure for most applications.
