Identifying optimal hash properties
In order for a hash algorithm to be effective, it must be able to generate a hash algorithm quickly and efficiently. In addition, it must have several other properties to provide the best security. An optimal algorithm must be able to stand the test of time and remain a solid algorithm, even with advances in technology.
In this section, we'll outline and explain some of the desired properties of an exceptional hash algorithm, such as non-reversibility, collision resistance, and determinism.
Let's start with the non-reversibility or one-way property.
Generating a one-way function
When we say one-way, we mean it. A variable-length block of data goes into the function, and a fixed-length hash is returned as the output. The output has no resemblance to the original block of data in any way. Nor is there any way to reconstruct the data to become the original. This non-reversible property is optimal as it makes a more secure hash...
