Frequently Asked Questions

Is my text sent to a server?

No. Hashes are computed entirely in your browser using the Web Crypto API — nothing is uploaded.

Which algorithms are supported?

MD5, SHA-1, SHA-256 and SHA-512. SHA hashes use the Web Crypto API; MD5 uses a small local library.

Should I use MD5 for passwords?

No — MD5 and SHA-1 are not secure for passwords. They are included for checksums and legacy compatibility.

Generate MD5, SHA-1, SHA-256 and SHA-512 hashes of any text online, free and live as you type. Toggle between lowercase and uppercase hex and copy any digest in one click. The SHA family is computed with the browser’s Web Crypto API and MD5 with a small local library, so your input never leaves your device. Useful for checksums, cache keys, fingerprints and verifying data integrity. Note: MD5 and SHA-1 are unsuitable for password storage.
