Description
The entropy source must be of high quality to guarantee the randomness of all underlying crypto systems.
Response Sequence
The primary use of randomness is the first time generation of the user's IMK and salt.
Requirements
PRNG-1. Any random data used for cryptographic functions must come from libsodium.
PRNG-2. The seed for the crypto randomness for generating the users IMK shall come from one of the devices sensors for at least 10 seconds and prompt the user to move the device around during those 10 seconds.
