# sha256sum
> Calculate SHA256 cryptographic checksums.
- Calculate the SHA256 checksum for a file:
`sha256sum {{filename1}}`
- Calculate SHA224 checksums for multiple files:
`sha256sum {{filename1}} {{filename2}}`
- Read a file of SHA256 sums and verify all files have matching checksums:
`sha256sum -c {{filename.sha256}}`
