checkasum

checkasum is a simple tool for hashing a file, and comparing the result with a known 'checksum' value. This allows the user to confirm the integrity of a file downloaded from the internet. If the value returned from hashing a file matches the given checksum, then chances are that the file has not been tampered with.

Examples

• checkasum -m sha256 -p /path/to/file -e somechecksum
• checkasum --method sha256 --path /path/to/file --expected somechecksum
