But in order for it to work properly, the PRNG must be initialized properly with a seed value that will determine the randomness of the value produced, ensuring the strength of the cryptography. Apparently, Android apps that use the Java Cryptography Architecture (JCA) only get weak cryptographic values because the PRNG isn’t being initialized properly, making those apps vulnerable to exploits.
