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

This is how I've always looked at it.

• Hashing is deriving a value from another, using a set algorithm. Depending on the algo used, this may be one way, may not be.

• Obfuscating is making something harder to read by symbol replacement.

• Encryption is like hashing, except the value is dependent on another value you provide the algorithm.
