What is the difference between 128 bit encryption and 256 bit encryption?

? 128 bits ?

Without a protocol/algorithm to go with it 128 or 256 are not types of encryption, they are just bit sizes/lengths. The bit length tends to refer to the size of prime being used and prime size is normally directly related to difficulty to factor / crack.

129 bit is twice as long as 128
130 is twice as long as 129

There is a common misconception that 256 is twice as hard to crack or twice as long compared to 128. It’s not, I CBA to do the maths but it’s LOTS bigger and LOTS more secure.

Could you also explain what is the difference between Hashing and Encryption? To me they pretty much sound the same. I was referring to AES earlier. Are there any other encryption protocols as well. Thanks for the reply.

You should check out these guys, they really explain this stuff, aim for high entropy that makes it harder to brute force any password.

Thanks very much, I will watch this soon.
