I have a DB that contains 150,000 12 char encrypted strings, I don't know the encryption mechanism and I am not sure if they have been salted. I'm basically wanting to explore the possibility of working out if the encryption can be reversed in a bulk process.
We know the 8 char strings that the encrypted text came from but they are on scanned PDFs and it would be a manual process to sort them which really is not an option.
I just wondered if anyone has any experience of this sort of thing, I am aware that there are tools that might be useful but really not sure where to start. I'm thinking maybe if we know the inputs and the output is only 12 chars then it could be reversed.
Obvious disclaimer that the data is ours and it's all above board, the code that did the encryption has been lost.
Cheers
