The question has the below multiple choices
A) 3DES
B) RSA
C) Blowfish
D) Twofish
The answer is (C)
Blowfish
Also known as the Blow-CAST-Fish
, it was designed to run efficiently on 32 bit computers. Up
to date no significant weaknesses have been seen. Based on Blow-CAST-Fish, it
uses good features of CAST -128[6] algorithms and Blowfish [1]. Features taken
from Blowfish [1] algorithm include; S-box entries which are key dependent
substitution, varying key lengths of up to 448 bits and procedure of Key
expansion
