Cryptographically secure PRNG (PseudoRandom Number Generator)
WebJan 6, 2015 · $\begingroup$ PRNG encompasses all pseudo random number generators, from the horrible rand call in c, over suitable for simulations but not security ones like the mersenne twister, to the most secure cryptographic PRNG. CSPRNGs are simply the subset of PRNGs which are secure. Every stream cipher, including AES-CTR can act as CSPRNG. … WebNov 2, 2009 · 3 Answers Sorted by: 126 using System.Security.Cryptography; ... using (RandomNumberGenerator rng = new RNGCryptoServiceProvider ()) { byte [] tokenData = … Webrandom next c# (13) . 為什麼有人會使用System.Random中的“標準”隨機數生成器,而不是總是使用System.Security.Cryptography.RandomNumberGenerator (或其子類因為RandomNumberGenerator是抽象的)的加密安全隨機數生成器?.
