I will try to help answer your very notice question in a way you can understand as you seem to be very new to this field.

CRC32 is not a security mechanism, it is an integrity mechanism. Sure bad security implementations by amateurs might do it. Data integrity is done through machine authentication codes or public private key security in a security context.

Its like asking would you use a Mersenne Twister pseudo random number generator as an algo in a security mechanism instead of a cryptographicly secure one. A product you've likely not encountered before called IDA Pro actually did use the MT PRNG for its key generation with 32 bit seeds which made a small state space to search for all possible keys.
