Another application is to build hash functions from block ciphers. (10 words)

Both hash functions are used to compute two table locations. (10 words)

In cryptographic hash functions, a Merkle–Damgård construction is usually used. (11 words)

If all hash functions are used and there is still a collision, then the key it collided with is removed to make space for the new key, and the old key is re-hashed with one of the other hash functions, which maps it to another bucket. (47 words)

Finding similar records main Hash functions can also be used to locate table records whose key is similar, but not identical, to a given key; or pairs of records in a large file which have similar keys. (37 words)

Hashing by nonlinear table lookup main Tables of random numbers (such as 256 random 32-bit integers) can provide high-quality nonlinear functions to be used as hash functions or for other purposes such as cryptography. (36 words)

Example sentences (20)

Multiplicative hash functions are simple and fast, but have higher collision rates in hash tables than more sophisticated hash functions.

These functions are categorized into cryptographic hash functions and provably secure hash functions.

In more realistic models, the hash function is a random variable over a probability distribution of hash functions, and performance is computed on average over the choice of hash function.

If all hash functions are used and there is still a collision, then the key it collided with is removed to make space for the new key, and the old key is re-hashed with one of the other hash functions, which maps it to another bucket.

It comes with a variety of hash functions and allows the use of runtime supplied hash functions via callback mechanism.

Just as block ciphers can be used to build hash functions, hash functions can be used to build block ciphers.

Hash functions used for data searches use some arithmetic expression which iteratively processes chunks of the input (such as the characters in a string) to produce the hash value.

Hashing by nonlinear table lookup main Tables of random numbers (such as 256 random 32-bit integers) can provide high-quality nonlinear functions to be used as hash functions or for other purposes such as cryptography.

Hashing with checksum functions One can adapt certain checksum or fingerprinting algorithms for use as hash functions.

Another application is to build hash functions from block ciphers.

Bloom filters are much more space-efficient than bitarrays in most cases and not much slower: with k hash functions, membership queries require only O(k) time.

Both hash functions are used to compute two table locations.

By combining multiple hash functions with multiple cells per bucket, very high space utilization can be achieved.

Caches Hash functions are also used to build caches for large data sets stored in slow media.

Finding similar records main Hash functions can also be used to locate table records whose key is similar, but not identical, to a given key; or pairs of records in a large file which have similar keys.

For example, Python adds the feature that hash functions make use of a randomized seed that is generated once when the Python process starts in addition to the input to be hashed.

Hash functions accelerate table or database lookup by detecting duplicated records in a large file.

However, this method suffers from a serious flaw: with most hash functions, it is easy to append data to the message without knowing the key and obtain another valid MAC (" length-extension attack ").

In cryptographic hash functions, a Merkle–Damgård construction is usually used.

In fact, even with good hash functions, their performance dramatically degrades when the load factor grows beyond 0.7 or so.
