uint32_t ndn::random::generateWord32

(

)

Generate a non-cryptographically-secure random integer in the range [0, 2^32)

This version is faster than generateSecureWord32, but it must not be used when cryptographically secure random integers are needed (e.g., when creating signing or encryption keys)
