Hi Jang,
I appreciate your response and detailed explanations!
I changed my mind - I would not replace the content with some bogus text as it may also change the amount of text lines present in files - and that's what I would like to avoid.
I would rather prefer to obfuscate the existing text, without changing its amount and flow.
Are you aware of any tools/APIs that can do that?
Thanks for your suggestions in advance!
