SHA hashes use the native Web Crypto API; MD5 and SHA-1 are included for legacy checksum workflows only. Both are broken for security, so never use them to store passwords. No data leaves your browser.

How it works

Type or paste text, or drop a file.
The MD5, SHA-1, SHA-256, and SHA-512 digests are computed instantly.
Copy the hash you need.
For files, the digest is computed over the file's bytes locally.

What people use it for

Verifying a downloaded file matches a published checksum.
Generating a SHA-256 of text for a quick integrity check.
Comparing two files by their hashes.

Good to know

MD5 and SHA-1 are provided for compatibility and checksums, but they are cryptographically broken. Do not use them for security.
A hash proves integrity, not authenticity; anyone can compute the hash of altered content.

Frequently asked questions

Which hash should I use?

SHA-256 is the safe default for integrity. MD5 and SHA-1 are only for matching legacy checksums, not for anything security-sensitive.

Can I hash a whole file?

Yes, drop a file and the digest is computed over its bytes in your browser, which is how you verify a download against its published checksum.

Is my text or file uploaded?

No. Hashing uses the Web Crypto API (and a local MD5 implementation) entirely in your browser.
