Hash Generator
Generate MD5, SHA-1, SHA-256 and SHA-512 hashes.
About the Hash Generator
A hash function turns any input into a fixed-length fingerprint. The same input always produces the same hash, but you cannot reverse a hash back into the original text. Hashes are used for verifying file integrity (checksums), indexing data and storing password representations. This tool generates MD5, SHA-1, SHA-256 and SHA-512 hashes from your text instantly, all locally in your browser.
How to use it
- Type or paste the text you want to hash.
- Watch all four hashes update as you type.
- Copy the hash you need with its Copy button.
Frequently asked questions
Which hash should I use?
Use SHA-256 or SHA-512 for security and integrity checks. MD5 and SHA-1 are fast but considered broken for security and should only be used for non-critical checksums.
Can I reverse a hash?
No. Hashing is one-way. Identical text always yields the same hash, but the hash cannot be turned back into the original input.
Is my input uploaded?
No. SHA hashes use the browser's Web Crypto API and MD5 runs in JavaScript — your text never leaves the page.
