Hash Generator
MD5, SHA-1, SHA-256, SHA-384 and SHA-512 — all five computed at once, live as you type. Click any hash to copy it.
How to use
- Type or paste text — all five hashes update live.
- Click any hash row to copy that digest to your clipboard.
- MD5 is computed by a built-in implementation; the SHA family uses your browser's native Web Crypto engine.
Frequently asked questions
Which hash algorithm should I use?
For integrity checks and fingerprints, SHA-256 is today's default. SHA-1 and MD5 are broken for security purposes (collisions are practical) but remain fine for non-adversarial checksums and legacy systems. SHA-512 is a good choice on 64-bit platforms.
Why does the same input always produce the same hash?
Hash functions are deterministic: identical input yields identical output on every machine. Change one character and the digest changes unpredictably — which is exactly what makes hashes useful for verification.
Can a hash be reversed to get the original text?
No. Hashing is one-way — the output does not contain enough information to reconstruct the input. What attackers do instead is try candidate inputs until one matches (brute force), which is why short or common passwords fall quickly even though the math is unbroken.
