This question already has an answer here:
So, this online discussion function use decoded account names in every post, along with that they call "logging data", an example of this can be:
Loggin data: 10878
Encoded account info: U2FsdGVkX19bCgrkbEjt4gDrFKNANCce
Now, the first part of the string when run through a base64 decoder ("U2FsdGVkX1") is just the string "Salted__" and the rest is what appears to be something binary.
So the account string changes for each input by the user, and what I am trying to do is to decode this string in order to determine if the value after "Salted__" is the same, and knowing that this is something that the owners of the software can do, I must assume that the "loggin data" is some sort of salt for the resulting binary data.
So, my question is - is there any way for me (or you) to figure out just how the binary data is encoded and how to decode it? And again - it can be decoded, as long as you know how. :)
This data does not (to my knowledge) contain any personal information and may at most contained the login name or the login ID of the user, so I am not trying to expose any personal information. Only determine whether someone is posting with multiple "nicks" from the same account.
