DateTime stamp or Code?

[madcat62]

Has anyone ever seen a date time stamp or code like this?

7CDE8F64DB88782E4EEEBF5DF6B84F034FEEBD54EBB1551E44F3BF5088C93E6B

That is a base64 encoded string. Decode it and you get a 48byte array:

Convert.FromBase64String("7CDE8F64DB88782E4EEEBF5DF6B84F034FEEBD54EBB1551E44F3BF5088C93E6B")

Looks like a 32 byte hash.

But sknake is more likely correct!

Thanks that helped get me started now I just have to figure out how they managed to get those 48byte array out of a date string "August 4, 2009". But at least now I'm on the right track and making progress.

Dates are stored in binary as a long which is 64 bytes so i'm guessing either it isn't a BASE64 string OR they're doing something tricky here. Is this a .NET application generating this hash/crypto string? If not then what language is it in?

It's a vb.NET app that a friend threw at me to take a look at. But I've been having problems making heads or tails of it. Pretty much it has a .exe and .ini the .ini has just two lines in it basically a [VarHead] and then the KEY="..." (what I posted earlier). It is possible that it's being hashed, I tried to pull the data binary but it kept throwing errors like crazy.

Upload the program you are referring to and i'll take a look at it

Just my guess. It's 256 bit AES key. They would be 64 hex characters (like you posted).
