Question

What is the difference between Obfuscation, Hashing, and Encryption?

Here is my understanding:

• Hashing is a one-way algorithm; cannot be reversed

Answer 1

Obfuscation is hiding or making something harder to understand.

Hashing takes an input, runs it through a function, and generates an output that can be a reference to the input. It is not necessarily unique, a function can generate the same output for different inputs.

Encryption transforms the input into an output in a unique manner. There is a one-to-one correlation so there is no potential loss of data or confusion - the output can always be transformed back to the input with no ambiguity.
