If you can break AES... then the NSA would love to have a word with you :P
The FBI is going after the lowest hanging fruit, the users password that was used to create the crypto key.
- superuser2 11y agoThe user's password is not used to create the crypto key; it is randomly generated and burned in at the factory.
- X-Istence 11y agoIt 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.
