Hash Generator
MD5, SHA-1, SHA-256, SHA-384 and SHA-512 for text or files.
Generate SHA-256 and other cryptographic hashes from text for free. Everything runs entirely in your browser — your files are never uploaded to a server, so your data stays private on your device.
A fingerprint for your data
A cryptographic hash turns any piece of text into a fixed-length string that acts like a unique fingerprint — change even a single character in the input and the resulting hash looks completely different. This makes hashes useful for checking that a password matches what was stored, confirming that a downloaded file or message hasn’t been altered or corrupted in transit, and generating consistent identifiers from text without storing the original content.
Picking an algorithm and comparing checksums
SHA-256 is the algorithm most commonly recommended today for integrity checks and general-purpose hashing, offering a strong balance of security and wide support; SHA-1 and others are also available for situations where you need to match an existing system. To verify a checksum, simply hash the content yourself and compare the result character-for-character with the one you were given — if they match exactly, the data is intact and unchanged.
How to use hash generator
- Paste the text to hash.
- Pick the algorithm (e.g. SHA-256).
- Copy the hash.
Frequently asked questions
Which algorithms are supported?
Common algorithms such as SHA-256 and SHA-1 via the browser’s native crypto.
Is my text sent to a server?
No — hashing runs locally in your browser.
Can I use it for checksums?
Yes, to verify content integrity by comparing hashes.
