Decoding method

jojoba20

my question is how to decode ( i dont have encoding method) : i got these from a website : d926ef0d-07df-3c5b-2246-12e061f71be1 ------> "0000000000" fd7bd272-f7e8-1e57-0a82-e15b79694d25 ------> "09130000000" 146b2bf5-fddb-5e68-0e9a-e5cdd19513dc ------> "0000000001" 4fb94dee-654f-55a5-5c94-71974b23fcd4 --------> "09130000001" b69ff890-e528-a2fc-c011-8f31dcfe4794 ----> "09125395974" f734f107-2d2c-b2e0-ed26-b92679d7cf68 ---> ? any decoding algorithm ? thanks in advanced!

They look like GUIDs (they are formatted that way, but of course one can format any old garbage like that so you can't really be sure what they are). So there might not be any way to decode them. Perhaps, and this is just speculation, the strings are stored in a table and associated with a GUID when first encountered. That would mean you can't really do anything without access to that table. That's the sort of thing that's done to prevent whatever it is you want to do.

The values on the left are GUIDs and bear no relation to the values on the right. What is this information and what are you trying to achieve?

There may be, but more likely not. Another possibility is that what is formatted as a GUID may simply be a 128-bit one-way hash of the value, in which case you can't "decode" it.

Is it possible to have encoding method? Thanks in advanced!

You are showing signs of optimism over experience: read the answers you have already, and try to think about what they are telling you. I will summarize them for you: Those look like GUID or Hash objects: neither of which is an encryption technique and neither of which can be decrypted as a result. So there is no encoding method, and no decoding method. And if you still can't work it out, here is an Executive Summary:

I have seen this in this page> it takes mobile and convert it to image and save it as file. http://divar.ir/new/[^]

What has converting the image got to do with the GUID's you linked earlier? Google translate refuses to translate the site. Can you explain me in simple terms what you're trying to achieve? Giving a bunch of random numbers and asking for a conversion, will never work. The numbers could represent anything. Now, converting a mobile webpage, a pdf, or a document to an image, that's something we could help with.

On the other hand, on the right side there are only 11-digit numbers. For 11-digit numbers, some 35 bits are sufficient (even when you encode it as ASCII characters, 88 bits are enough). If the process of generating the Guid uses that 11-digit number only (and nothing else) as an input, then a reversal of the process could be theoretically possible: no information need to be lost during that process. But that's surely not easy to find out how they did it.

By the way, are you also Member 9473809[^]? That guy posted the same idea in the ASP.Net forum just a few days ago, see http://www.codeproject.com/Messages/4882150/Get-original-string-from-Guid.aspx[^].

Yes, but then the leading bits would probably be all zeroes.
