HASH VALUE [9 records]

Record 1 2024-02-23

English

Subject field(s)
  • IT Security
  • Computer Mathematics
  • Probability (Statistics)
CONT

In cryptography, a collision attack on a cryptographic hash tries to find two inputs producing the same hash value, i. e. a hash collision.

French

Domaine(s)
  • Sécurité des TI
  • Mathématiques informatiques
  • Probabilités (Statistique)
CONT

En cryptographie, une attaque de collisions est une attaque sur une fonction de hachage cryptographique qui tente de trouver deux entrées de cette fonction qui produisent le même résultat (appelé valeur de hachage), c'est-à-dire qui résultent en une collision.

English

Subject field(s)
  • Computer Mathematics
  • Information Processing (Informatics)
  • Computer Programs and Programming
CONT

Hash tables are a type of data structure in which the address/index value of the data element is generated from a hash function. This enables very fast data access as the index value behaves as a key for the data value.

English

Subject field(s)
  • Codes (Software)
  • Computer Programs and Programming
CONT

Hashability makes an object usable as a dictionary key and a set member, because these data structures use the hash value internally.

English

Subject field(s)
  • Codes (Software)
  • Computer Programs and Programming
CONT

Immutable objects include numbers, strings and tuples. Such an object cannot be altered. A new object has to be created if a different value has to be stored. They play an important role in places where a constant hash value is needed, for example as a key in a dictionary.
