WebPseudo-random number generators (PRNGs) are algorithms that can create long runs of numbers with good random properties but eventually the sequence repeats. Thus, the term ‘pseudo’ random number generators. The algorithms essentially generate numbers that, while not being truly random, are random enough for cryptographic applications.

WebNov 3, 2009 · Cryptanalysis of the WinAPI GUID generator shows that, since the sequence of V4 GUIDs is pseudo-random, given the initial state one can predict up to the next 250 000 GUIDs returned by the function UuidCreate. This is why GUIDs should not be used in cryptography, e.g., as random keys. (from en.wikipedia.org/wiki/Globally_Unique_Identifier)
