Examples of hashinghashing Another generalization of cuckoo hashing consists in using more than one key per bucket.

Cuckoo hashing, another technique for implementing hash tables, guarantees constant time per lookup (regardless of the hash function). From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Like all other forms of open addressing, double hashing becomes linear as the hash table approaches maximum capacity. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Furthermore, hashing is applied to passwords for computer systems. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In this type of attack, the program goes through all the possible plaintexts, hashing each one and then comparing it to the input hash. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The hashing function is not generally optimized for coverage - raw speed is more desirable. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Some secure environments employ cryptographic hashing, simply to verify that the information has not been altered since it was last modified. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Linear hashing allows for the expansion of the hash table one slot at a time. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Linking-based time-stamping scales well - hashing is much faster than public key cryptography. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Hence consistent hashing is needed to avoid swamping of servers.
