These three categories of cryptographic algorithms are indeed commonly used to create Pseudo-Random Number Generators (PRNGs). Symmetric block ciphers can be used in modes that generate pseudo-random output from a fixed key. Asymmetric ciphers, although less common for PRNGs due to their computational complexity, can also be used to generate randomness. Hash functions and message authentication codes (MACs) are frequently used in the construction of PRNGs because they can take an input and produce a seemingly random output, which is difficult to predict without knowing the input.
