How Client-Side bcrypt & Cryptographic Hashing Works
bcrypt & Hash Generator (SHA-256, SHA-512, SHA-1, MD5) runs entirely in your browser with JavaScript. There is no sign-up, and whatever you type or open here is processed on your device instead of being sent to a server.
Generate Strong Password Hashes Locally in Your Browser
Generate secure bcrypt hashes with a cost factor of 4, 8, 10, 12 or 14 directly inside your browser memory. Because password hashing executes on-device, your plaintext passwords and salt strings are never sent across the internet.
Cryptographic Hash Suite: SHA-256, SHA-512, SHA-1 and MD5
In addition to bcrypt, generate instant one-way cryptographic digests using SHA-256 and SHA-512 powered by the browser Web Cryptography API. Legacy MD5 and SHA-1 hashes are also available for checksum verification. The SHA and MD5 hashes are computed for the text in the single-line box: there is no file input and line breaks in pasted text are not kept, so use a file checksum tool to check a downloaded file.
Mobile-Friendly Input Protection
The input field automatically disables mobile autocorrect and capitalization to ensure you hash exact intended character sequences without unexpected initial capitals.
Why processing in your browser matters
Many online tools upload your files or text to a server to process them. This one does the work on your computer or phone, so your data is not sent to us or stored anywhere else. That lowers the risk when you work with confidential material, although you should still follow your organisation's own rules. Read how this works in our Privacy Policy.
- No uploads: files are opened and saved on your device, so there is no upload or download wait.
- No account: nothing to sign up for or install.
- Free to use: no subscriptions or paywalls.
