Generate checksum

$ checksum package.json --algorithm sha256
> b6f69eb6fcf34f5f3e9b34724562b7c6b681f6b2aeefc7909363930febd5da83

$ checksum package.json README.md --algorithm md5

$ checksum -C "Hello World" --algorithm md5
> b10a8db164e0754105b7a99be72e3fe5

$ echo -n "Hello World" | checksum --algorithm sha1
> 0a4d55a8d778e5022fab701977c5d840bbc486d0

Verify checksum

$ checksum verify package.json b6f69eb6fcf34f5f3e9b34724562b7c6b681f6b2aeefc7909363930febd5da83
> match

$ echo -n "56bfa638dc6449196cf8110d693b6dab" | checksum verify package.json -a md5
> match

$ echo -n "WRONG" | checksum verify package.json -a md5
> mismatch: expected 56bfa638dc6449196cf8110d693b6dab but got 0a4d55a8d778e5022fab701977c5d840bbc486d0
