WebIn order to be cryptographically strong, the pseudo-random running key must be unpredictable. The main problem is to guarantee that even when the cryptanalyst obtains long segments of the running key (by XOR'ing together known cleartext/cypher- text pairs) he should have no knowledge whatsoever about any other segment. ... WebJun 29, 2024 · Cryptographically strong RNG. Along with a standard RNG method, programming languages usually provide a RNG specifically designed for cryptographic operations. This method is usually much more secure, because it draws entropy straight from the operating system. The result of such RNG is much harder to reproduce.
