Why hashes show up everywhere

A hash is a fingerprint of data that changes entirely if even a single byte is different. That property makes it the standard tool for checking that a file has not been tampered with, for verifying a password without storing it in plain text, and for telling quickly whether two pieces of data are identical.

This tool converts your text into MD5, SHA-1, SHA-256, and SHA-512 digests in a single pass and lays them out side by side. A copy button next to each hash sends it straight to the clipboard, and every calculation runs locally in your browser so the input never leaves your device.

Who gets the most out of it

  • Verifying file downloads — comparing a hash against the published checksum
  • Backend and security developers — building password verification or signature values
  • DevOps and infrastructure engineers — recording hashes of configs and build artifacts
  • Data analysts — telling quickly whether two datasets are identical

Choosing the right algorithm

MD5 and SHA-1 are fast, but collisions have been found, so they are no longer recommended for security-sensitive uses. Reach for SHA-256 or stronger whenever passwords or signatures are involved. MD5 is still fine for checksums and quick comparisons.

Frequently asked questions

No. Hashing happens entirely in your browser. The text you enter is never transmitted to or stored on a server, so it is safe to hash sensitive values such as passwords.

MD5, SHA-1, SHA-256, and SHA-512. SHA-1/256/512 use the browser's built-in Web Crypto API, while MD5 uses a self-contained implementation.

Use SHA-256 or stronger for anything security-sensitive. Collisions have been found in MD5 and SHA-1, so they are no longer recommended for passwords or signatures. For simple checksums and deduplication, MD5 remains usable.

This tool handles text input only. To hash a file, open it and paste the contents, or use a dedicated file-hashing tool.

Yes. The text is converted to UTF-8 bytes before hashing, so Korean, Japanese, emoji, and other multibyte characters are all handled consistently. The same string always produces the same hash.
