They rely on\n\t\t   cryptographically secure and unique seeds for entropy so\n\t\t   proper seeding is critical to the secure operation of the\n\t\t   PRNG.\nManagement of seeds could be broken down into two main areas:\nPRNGs require a seed as input to generate a stream of\n\t\t\t   numbers that are functionally indistinguishable from\n\t\t\t   random numbers.  While the output is, in many cases,\n\t\t\t   sufficient for cryptographic uses, the output of any\n\t\t\t   PRNG is directly determined by the seed provided as\n\t\t\t   input. If the seed can be ascertained by a third party,\n\t\t\t   the entire output of the PRNG can be made known to\n\t\t\t   them. As such, the seed should be kept secret and\n\t\t\t   should ideally not be able to be guessed. For example,\n\t\t\t   the current time may be a poor seed. Knowing the\n\t\t\t   approximate time the PRNG was seeded greatly reduces\n\t\t\t   the possible key space.\nSeeds do not necessarily need to be unique, but reusing seeds may open up attacks if the seed is discovered.","Draft","Base","Simple",1,false,[],{"title":77,"metaDescription":78,"keywords":79,"canonicalUrl":80,"structuredData":81},"What is CVE-2020-13784?
