How to generate a hash
- Type or paste text, or choose a local file up to 100 MB.
- All four SHA hash variants update after the input is read.
- Click copy next to any result.
Why use this private hash generator?
Your text stays in your browser. Hashes are computed using the browser's built-in Web Crypto API, the same cryptographic implementation used by the browser itself.
About MD5
MD5 is not included. It isn't natively supported by the Web Crypto API, and it's considered cryptographically broken for security purposes — SHA-256 or SHA-512 are the modern standard choices.
Common use cases
- Generate a SHA-256 checksum for a piece of text
- Compare two files' hashes to confirm they match
- Create a hash for an API signature or integrity check
Frequently asked questions
Is this hash generator free?
Yes, with no signup or watermark.
Is my text uploaded anywhere?
No. Hashing runs entirely in your browser via the Web Crypto API.
Which hash algorithms are supported?
SHA-1, SHA-256, SHA-384, and SHA-512.
Why isn't MD5 supported?
The Web Crypto API doesn't implement MD5, and it's no longer considered secure. Use SHA-256 or SHA-512 instead.
Can I hash a file instead of text?
Yes. Choose a local file up to 100 MB. It is read and hashed in your browser without being uploaded.
