The non-cryptographic hash functions (NCHFs[1]) are hash functions intended for applications that do not need the rigorous security requirements of the cryptographic hash functions (e.g., preimage resistance) and therefore can be faster and less resource-intensive.[2] Typical examples of CPU-optimized non-cryptographic hashes include FNV-1a, Murmur3.[3] Some of the non-cryptographic hash functions are used in the cryptographic applications (usually in combination with other cryptographic primitives), in this case they are described as universal hash functions.[4]
