Trace Output

2024-02-05T08:28:09-05:00	info-1	trufflehog	binary file not handled, chunking raw	{"path": "example.PNG"}
2024-02-05T08:28:09-05:00	info-1	trufflehog	binary file not handled, chunking raw	{"path": "example2.PNG"}

Expected Behavior

TruffleHog should ignore .png files.

Actual Behavior

TruffleHog scans PNG files if they have an uppercase extension (.PNG). The function SkipFile should use a case-insensitive comparison like string.EqualFold.

trufflehog/pkg/common/vars.go

Lines 89 to 96 in a22874f

	func SkipFile(filename string) bool {
	for _, ext := range IgnoredExtensions {
	if strings.TrimPrefix(filepath.Ext(filename), ".") == ext {
	return true
	}
	}
	return false
	}

Steps to Reproduce

1. Change the extension of a .png, or any other ignored file type, to uppercase.
2. Scan the file.
3. The file will be chunked instead of skipped.
