Hash Generator
5 algorithms, instant computation
—————⚠️ MD5/SHA-1 are unsafe for security; use Argon2, bcrypt, or scrypt for passwords
Quick guide
What can Hash Generator (MD5/SHA) help you do?
Free online hash generator using Web Crypto API. Supports MD5, SHA-1, SHA-256, SHA-384, SHA-512.
Best for
Compare text, make a non-security cache key, or check a supplied digest. It returns MD5, SHA-1, SHA-256, SHA-384, and SHA-512, not file hashes.
How to use it
Paste exact text into Input Text; all five hashes update at once. Use each Copy button; case, spaces, and line endings all change the result.
How to read the result
Hex lengths are 32, 40, 64, 96, and 128 for MD5 through SHA-512. Equal hashes compare text but do not prove authorship.
Privacy and limits
SHA uses Web Crypto and MD5 runs locally. Never enter production secrets, passwords, private keys, or personal data.
MD5 and SHA-1 have collision risks. For passwords use Argon2, bcrypt, or scrypt, not plain SHA-256.
Frequently Asked Questions
What is a hash?
A one-way function turning data into a fixed-length string. Used for checksums, signatures, password storage.
Is MD5 still safe?
MD5 has known collision attacks — not for security uses. OK for checksums or cache keys.
