About srisum

srisum is a minimal command-line tool to compute and display the Subresource Integrity checksum of a local file or a remote file accessible via an HTTPS URL.

That is useful in at least these two contexts:

• Adding new static file asset to an existing HTML document
• Bumping a nixOS package for nixOS from a non-nixOS host

srisum is software libre written in Python 3 and licensed under the MIT license.
