@cumulus/checksum
Advanced tools
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.
const fs = require('fs');
const { generateChecksumFromStream } = require('@cumulus/checksum');
const stream = fs.createReadStream('myDataFile.hdf');
const myCksum = generateChecksumFromStream('cksum', stream);
Promise.<(number|string)>Promise.<boolean>Promise.<(number|string)>Create file checksum from readable stream
Kind: static method of checksum
Returns: Promise.<(number|string)> - the file checksum
| Param | Type | Description |
|---|---|---|
| algorithm | string | Checksum algorithm type |
| stream | stream.Readable | A readable file stream |
| [options] | Object | Checksum options, see crypto.createHash() |
Promise.<boolean>Validate expected checksum against calculated checksum
Kind: static method of checksum
Returns: Promise.<boolean> - whether expectedSum === calculatedSum
| Param | Type | Description |
|---|---|---|
| algorithm | string | Checksum algorithm |
| stream | stream.Readable | A readable file stream |
| expectedSum | number | string | expected checksum |
| [options] | Object | Checksum options |
