Makes me wonder how they found this one. Did they just point it at one random place and happened to find this galaxy there, or did they have to look around for a long time.
If we take that telescope array and point it at a new random place will we just find another one of these galaxies in short order?
It is used to create the crypto key, using a password based key derivation function, using the user's password fed into the PBKDF the output is the key used for encryption/decryption.
The users device key is mixed into that PBKDF. Without both parts of the equation, you have nothing.
