WebCryptographically secure hash functions have the requirement of being collision resistant. Collision resistance is achievable even if the output is biased. If you make the additional … WebFor a value to be cryptographically secure, it must be impossible or highly improbable for an attacker to distinguish between it and a truly random value. In general, if a PRNG algorithm is not advertised as being cryptographically secure, then it is probably a statistical PRNG and should not be used in security-sensitive contexts. Examples

Webpublic class SecureRandom extends Random This class provides a cryptographically strong random number generator (RNG). A cryptographically strong random number minimally complies with the statistical random number generator tests specified in FIPS 140-2, Security Requirements for Cryptographic Modules , section 4.9.1. WebIf you want a lot of pseudorandomness with a very high bandwidth, you should look at specialized stream ciphers like these ones (a stream cipher can be turned into a PRNG by making it encrypt a long sequence of zeros).

WebInitialization vectors must be chosen appropriate for the mode of operation. For 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.
