# checksum

A command line tool to check and correct the Portable Executable (PE) file checksums.

### Usage

```

Usage: checksum [--check] [--quiet] [--no-backup]  [[file] ...]

checksum fixes the Portable Executable (PE) checksum for 32-bit and 64-bit binaries.

Options must be provided before the list of files:

    --check     - perform checksum validation only.

    --quiet     - suppress non-error output.

    --no-backup - suppress creation of backup files.

The exit code meaning:

    Number of files with invalid checksum that were not updated.

    Number of files with invalid checksum when running with --check.

```

### Use Cases

1. Correct invalid checksums of portable executable (PE) files after binary patching.
