WebFor many modes, this means using a CSPRNG (cryptographically secure pseudo random number generator). For modes that require a nonce, then the initialization vector (IV) does not need a CSPRNG. In all cases, the IV should never be used twice for a fixed key. Always use authenticated encryption instead of just encryption. WebHere is the Pseudorandom Number Generator written in C# on a project for Cryptographic Techniques of Information Security at my University. It also contains the NIST test to check generator's cryptographic quality. The generator is based on the three linear feedback shift registers (LFSR): LSFR-1 of length 27 (the tapped bits are 1, 2, 5, 27),
