in thread encrypt passwords

In summary, even you are admitting that without compromise, your only recourse is to tell your boss 'no'.

If you aren't going to tell your boss 'no', the remaining choice is to compromise and get the cleartext passwords out of the module as requested. It's a feeble endeavor, to be sure, but it satisfies the request under its given constraints.

You have offered no alternative; in the absence of one, what is given is considered sufficiently proven for management.

Now -- I concur that under those constraints, the system cannot be unbroken. I argue that it can be made, however marginally, better.

Yes, someone who speaks Perl (or any of a dozen other C-like languages) will probably be able to hack the passwords if they have access to the module. But that does add a layer of knowledge required.

As they say in some southern regions in the USA, "It ain't much -- but it ain't nuthin'."

All of this is moot in the face of the actual task requested: Get the cleartext passwords out of the Perl module.

However stupid, however, moronic, however pointless, ultimately your job is to advise your boss, and then to do what your boss says -- or leave.

Those skilled in manipulating the politics and culture of a company have additional options; these are not directly available to me. I couldn't sell water to a rich man crawling across the Arizona desert.

I could write a Perl script to find the closest convenience store, though.

    If that's your summary, you didn't read what I wrote.

    You don't tell your boss: "No!". You tell your boss: "There are things we could do, but there is no point in doing them." And then you explain why.

    You have offered no alternative

    I have. Fix the authentication mechanism. Properly.

    To get into the detail of how to go about that would require much more than your vague description.

    Sorry, but protecting against those with no skills is like wearing a pinafore in a war zone.

    And offering obfuscation as security is tantamount to fraud.

      As usual, I have no particular argument with the facts you have presented; only that you are ignoring facts presented to you.

      You tell your boss the right way to fix it. He says,

            "Well, Mike Richardson owns that server. He set it up, his people maintain it, and we've asked him to change authentication to something which can be globalized. But he won't budge. And my management won't back me on trying to force him to change the way he does business -- it just isn't in our corporate culture.      
       
      However, they do have a bug up their behind about getting cleartext passwords out of this module.
       
      Short of revamping the entire system, which I cannot do, what can you do for me to meet this requirement?"

      So, esteemed BrowserUk, I ask you again -- laying out more fully what I suspect you were smart enough to know was my point all along -- what is your response in this hypothetical situation? Is this really the issue you'd really stand tall on and stake your career path, or would you be inclined to bend a little, and help your boss?

      And, assuming you don't choose to tender your resignation (or at least put the nail in the coffin of your future with this company), what would your approach be toward developing a solution for your boss?

      Which comes as close as I dare to presenting a condition which might require the assistance requested by the OP.

        1. I'd tell him the truth.

          Depending upon my read of the situation and the man, I'd likely do it in the form of a formal report.

          If I felt it necessary, I'd copy his boss on it.

        2. I'd demonstrate that any pure Perl solution is trivially defeated with minimum effort and knowledge.

          I'd hide a password behind 3 levels of secure encryption, and run the script as:

          perl -d:Trace theScript.pl | find "DBI->connect"

          [download]

          And watch the decoded password pop into view.

        3. I'd then offer him a binary solution as a "stop gap" measure, to be used at his own risk.

          And I'd want pre-absolution for any and all failures; in writing, before I coded it.

        What would your approach be to developing a solution for your boss to a problem for which a primary requirement of a solution is that there be no actual solution of the problem?

        One approach might be to forthrightly declare that there can be no solution to a problem which is required to have no solution. You then take the hit to your "future", such as it is, with this company.

        Another approach would be to deposit your personal and professional integrity alongside your boss's in the receptacle in which it now moulders, and confidently declare that the problem can, indeed, be solved by the application of sufficient snake oil — and you have just the snake oil needed. You then immediately start looking around for some co-worker whom you can set up to use as the fall-guy when the "solution" you will provide collapses in the face of the first real test of adversity it encounters. If you are sufficiently Machiavellian, you may, as poetic justice and for extra points, be able to set up your boss as the patsy. Be assured that your boss already has you marked down for this position!

        In any event, you start prospecting for the next step on your career path, recognizing that all the nails are already solidly hammered home in the coffin of your future with this benighted company. (And who's the president of this hypothetical outfit anyway? Tom Ripley?)
