checksum

checksum - Command line file checksum validator.

### Determine a checksum for a file

checksum checks a file and returns a checksum for md5, sha1, and sha2 (sha256 and sha512).

To use checksum you would simply provide a file path and it will return the sum for the file.

#### Examples

* `checksum -f="relative\path"`

* `checksum "relative\path"`

* `checksum -f="c:\absolute\path" -t=sha256`

### Validate a file against an existing signature

You can also check against an existing signature.

To validate against an existing signature (hash) you would simply provide the file and the expected signature. When checking a signature, if the signature is valid it exits with 0, otherwise it exits with a non-zero exit code.

#### Examples

* `checksum -f="c:\absolute\path" -c=8AC4EA9A7B18E67EA97088220C40041B355A2C3049AA4E290D1F65A94BEFA9EF`

* `checksum -f="c:\absolute\path" -c=8AC4EA9A7B18E67EA97088220C40041B355A2C3049AA4E290D1F65A94BEFA9EF -t sha256`
