Hash Generator — MD5, SHA-256, SHA-512

Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from text. Free, no signup, works in your browser.

All hashing happens in your browser using the Web Crypto API. No data is sent to any server.

About Hash Generator

This hash generator computes five popular cryptographic hash functions at once: MD5, SHA-1, SHA-256, SHA-384, and SHA-512. Type or paste any text and all five hashes appear in real time. Click any hash to copy it. SHA-256 and SHA-512 use the browser's built-in Web Crypto API for speed and accuracy; MD5 uses a lightweight JavaScript implementation. Hashes are commonly used for verifying file integrity, storing password digests, generating checksums, and creating unique identifiers.

Frequently Asked Questions

What is the difference between MD5 and SHA-256?
MD5 produces a 128-bit (32-character) hash and is fast but no longer considered cryptographically secure. SHA-256 produces a 256-bit (64-character) hash and is part of the SHA-2 family used in SSL certificates, Bitcoin, and many security protocols.
Can I reverse a hash back to the original text?
No. Cryptographic hash functions are one-way — you cannot recover the original input from a hash. This is by design and is what makes hashes useful for password storage and data integrity.
Is my text safe?
All hashing runs entirely in your browser using the Web Crypto API. Your text never leaves your device — nothing is sent to any server.
