Hash Generator (MD5, SHA-1, SHA-256)

About this hash generator

A hash function turns any input into a fixed-length string that changes completely with the smallest input change. Hashes are used for checksums, cache keys, deduplication, and verifying downloads. Paste text and get its MD5, SHA-1, SHA-256, and SHA-512 digests at once, ready to copy.

Frequently asked questions

Which hash algorithms are supported?

MD5, SHA-1, SHA-256, and SHA-512. SHA hashes use the browser's built-in Web Crypto API; MD5 is computed in the browser as well.

Is my input sent to a server?

No. Hashing runs entirely in your browser, so the text you hash never leaves your device.

Should I use MD5 or SHA-1 for security?

No. MD5 and SHA-1 are broken for security purposes and should only be used for checksums or non-security identifiers. Use SHA-256 or SHA-512 when collision resistance matters.
