What is a .SHA1 file?

The most common data format on the web.

A .sha1 file is a small plain-text file containing a 40-character SHA-1 fingerprint of another file (an ISO, installer, or archive). You use it to confirm your download arrived without corruption: compute the SHA-1 hash of your file and compare it to the value inside. On Windows run `certutil -hashfile yourfile.iso SHA1`; on macOS run `shasum yourfile.iso`; on Linux run `sha1sum -c file.sha1`. SHA-1 has been cryptographically broken since 2017 and cannot prove a file was not maliciously replaced.

Frequently asked questions

Is my .SHA1 file uploaded anywhere?

No. The file is opened directly from the copy you pick.

My .SHA1 file is invalid. Can you fix it?

We show the exact line and column of the first error. For common problems like comments, trailing commas, single quotes or Python-style True/False/None, click Try to repair and download the fixed file.

How large can the file be?

Up to 50 MB. The tree only builds the branches you open, so even multi-megabyte files stay responsive.

What is JSONPath?

A path like $.orders[3].customer.email that points to one value inside the data. Click any node to see its path and copy it for code, jq or your API docs.

Can I see my data as a table?

Yes. Any array of objects can be shown in the Table view and downloaded as CSV.
