Tuning of the hashfunction parameters leads to many variations. The complexity of the function called depends on the connectionist model used, and may be comparable to a simple hashfunction sometimes. Uses a brute-force search to construct a perfect hashfunction for a set of 16 keywords. 150 lines. There is however a simple and much faster algorithmic solution - using a trivial hashfunction table lookup. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. For example, each encryption key can be generated from the underlying key material using a cryptographic hashfunction or other key derivation function.

The most secure don't store passwords at all, but a one-way derivation, such as a polynomial, modulus, or an advanced hashfunction. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. There exists a known weakness in the hash based key stretching algorithms that use an iterative hashfunction. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Only the collision attacks are of practical complexity; none of the attacks extend to the full round hashfunction. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. See hashfunction for a much more detailed discussion. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A rolling hash is a hashfunction specially designed to enable this operation. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. When a collision attack is discovered and is found to be faster than a birthday attack, a hashfunction is often denounced as broken. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Because the check value has a fixed length, the function that generates it is occasionally used as a hashfunction. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The technique is known as a trivial hashfunction or, when used specifically for branch tables, double dispatch. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Cuckoo hashing, another technique for implementing hash tables, guarantees constant time per lookup (regardless of the hashfunction). From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A poor hashfunction can exhibit poor performance even at very low load factors by generating significant clustering. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A key collision is the hashfunction mapping of different keys to the same position in a hash table. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. On top of that, it is possible for the secondary hashfunction to evaluate to zero. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The downside is extra latency from computing the hashfunction. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This analysis makes the (unrealistic) assumption that the hashfunction is completely random, but can be extended also to 5-independent hash functions. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Central to this is the capacity of the hashfunction, which is the state bits that are not touched by input or output.
