Hash Generator
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes of any text.
How to use the Hash Generator
Step 1 — Enter text
- Type or paste the text you want to hash.
Step 2 — Choose algorithms
- Tick any of MD5, SHA-1, SHA-256, SHA-512.
Step 3 — Generate
- Press Generate; each hash appears with a copy button.
Private
- Hashing happens in your browser; nothing is uploaded.
Frequently asked questions
MD5, SHA-1, SHA-256, and SHA-512. You can generate any combination at once and copy each result.
Verifying data integrity (checksums), comparing files or strings without revealing them, and as building blocks in many systems. Note that MD5 and SHA-1 are not secure for passwords.
No. For passwords use a purpose-built algorithm such as bcrypt or Argon2 with a salt. MD5 and SHA are general-purpose hashes and are too fast to resist password cracking.
Yes. A hash is deterministic, so identical input always produces identical output — that is what makes hashes useful for verification.
No. SHA hashes use your browser built-in crypto and MD5 runs in JavaScript locally. Nothing leaves your device.
About the Hash Generator
This tool computes cryptographic hashes of any text — MD5, SHA-1, SHA-256, and SHA-512 — directly in your browser. A hash is a fixed-length fingerprint of input data: feed in the same text and you always get the same hash, but change a single character and the hash changes completely.
What hashes are for
Hashes are everywhere in computing. The most common everyday use is verifying integrity: a download site publishes the SHA-256 of a file so you can confirm yours was not corrupted or tampered with. Hashes also let systems compare or index data without storing the original, and they underpin digital signatures, version control, and content-addressed storage. The different algorithms produce different-length fingerprints — MD5 is 32 hex characters, SHA-256 is 64 — with the longer, newer ones being more collision-resistant.
An important security note
These are general-purpose hashes, not password hashes. MD5 and SHA-1 in particular are considered broken for security purposes — collisions can be engineered — so they should only be used for non-security checksums, never to protect passwords. Even SHA-256 is unsuitable for passwords on its own because it is fast to compute, which helps attackers. For storing passwords, use a deliberately slow, salted algorithm such as bcrypt, scrypt, or Argon2. This tool is for checksums, comparisons, and learning, not credential storage.
How it works here
The SHA family is computed using the cryptographic functions built into modern browsers, and MD5 is computed in JavaScript. All of it runs locally, so the text you hash never leaves your device. You can generate several algorithms at once and copy each result independently.
