Files are processed in your browser. Nothing is uploaded to a server.
A hash is a fixed-length fingerprint of any input. The same text always produces the same hash, but you cannot reverse a hash back into the text. Developers use hashes to verify file integrity, build cache keys and compare values without storing the originals.
This tool generates several hash types from any text you paste.
How to generate a hash
- Paste the text you want to hash.
- The MD5, SHA-1, SHA-256 and SHA-512 digests appear instantly.
- Copy whichever hash you need.
- Compare it against an expected value to verify integrity.
Hash algorithms at a glance
| Algorithm | Length | Recommended for |
|---|---|---|
| MD5 | 128-bit | Non-security checksums only |
| SHA-1 | 160-bit | Legacy; avoid for security |
| SHA-256 | 256-bit | General-purpose, secure |
| SHA-512 | 512-bit | High-strength fingerprints |
For passwords, plain hashes are not enough — use a dedicated, salted algorithm like bcrypt or Argon2 on the server.
Generator features
- Computes MD5, SHA-1, SHA-256 and SHA-512 together.
- Updates live as you edit the input.
- Lowercase hexadecimal output, ready to compare.
- Hashing runs in your browser, so the input stays private.
Frequently asked questions
Can a hash be reversed?
No. Hashing is one-way. You can only confirm a match by hashing the candidate input and comparing the results.
Is MD5 safe?
Not for security — it is broken against collisions. It is still fine as a quick checksum for detecting accidental changes.
Should I hash passwords with this?
No. Password storage needs a slow, salted algorithm (bcrypt, scrypt, Argon2) handled server-side, not a plain fast hash.
