Sha1-service is a project mainly written in ..., it's free.
Micro-service to generate sha1 checksums
h1. sha1-service
This service allows you to post a url that points to a file. The service will then download that file, run it through sha1sum and return the checksum.
Example:
This would generate sha1 checksum for the content of the "original" datastream in a Fedora object with pid chagneme:20
http://localhost:3000/sha1?url=http://localhost:8983/fedora/objects/changeme:20/datastreams/original/content
