Hash generator

How to use this tool

Calculate SHA-2, SHA-3, MD5, RIPEMD160 and SHA-1 hashes.

Paste or enter your content. The result updates as you type. Choose an option only when you need to change the default.

SHA-1 is included for legacy compatibility. Hashes are not encryption; use a password-specific algorithm when storing passwords.

Your input stays in this browser. Drafts are kept in page memory while switching tools, and disappear on reload.

Text is limited to 1 million characters. Regex runs in a worker, capped at 200,000 characters, 1,000 matches and 1.5 seconds. Inputs above 100,000 characters use manual refresh.

The first page load and on-demand modules require network access. A complete offline cache is not included.
