# File Name This generator scrambles characters, but preserves formatting and keeps the file extension intact. For example, for the following input value: `DataSummary1.pdf` The output value would look something like: `RsnoPwcsrtv5.pdf` This generator securely masks letters and numbers. There is no way to recover the original data. ## Characteristics
