Hashing
Hashing refers to the hash algorithms used in cryptography. It is used to store data,
such as hash tables and its main characteristics are: It must be one-way – it is not
reversible. Variable-length input produces fixed-length output – whether you have two
characters or 2 million, the hash size is the same. The algorithm must have few or no
collisions – in hashing two different inputs does not give the same output.
Phản hồi
Your answer is correct.
