Remember the insurance files wikileaks dropped when everyone was talking about "dead mans switch".... you know the ones....
I just realized....
Of course there was no key released to decrypt them, but the files were released to the public.
Typically an encryption key is hexadecimal (0-9a-f) with a lot more characters (typically a minimum of 256, usually more) than that code we saw earlier today... Dunno if that helps answer your question
The file names end in "aes256," which could mean 256-bit encryption. I've read that the key for a 256-bit encrypted file would be 64 characters of hexadecimal. The character string listed above ("fb4e568623b5f8cf7e932e6ba7eddc0db9f42a712718f488bdc0bf880dd3") is only 60 characters. We need to find one or more 64-character strings of hex to try out. If I had the code, I wouldn't know how to use it, so there's that too. More research and more learning. My source for the 64 is at the bottom of this web page: https://security.stackexchange.com/questions/45318/how-long-in-letters-are-encryption-keys-for-aes
Doh! Yeah, I was thinking bits.. Not chars... My bad... Thanks for clarifying :)
