Cumulus Documentation

Checksum

The @cumulus/checksum library provides checksum functionality used by Cumulus packages and tasks. Currently the supported input includes file streams, and supported checksum algorithms include cksum and the algorithms available to the crypto package, as documented here.

Usage

const fs = require('fs');
const { generateChecksumFromStream } = require('@cumulus/checksum');

const stream = fs.createReadStream('myDataFile.hdf');
const myCksum = generateChecksumFromStream('cksum', stream);
