Blowfish Encryption Algorithm
...encryption or decryption process carries out. In an example below, let’s assume that P is pre-calculated array consisting of 18, 32 bit sub keys from P1, P2… till P 18. In addition, there are S boxes (32 Bit) indicated by S with entries equal to 256 each (Hancock,PhD, CISM, John Rittinghouse, PhD, CISSP, CISM,William M. n.d). S1, 0, S1, 1…S1, 255; S2, 0, S2, 1….S2, 255; S3, 0, S3, 1…S3, 255; S4, 0, S4, 1….S4, 255; The sub key calculation process is calculated by deploying the following algorithm (Hancock,PhD, CISM... ?Introduction Information system security is becoming a dominant and challenging factor for organizations, as it leverages many risks that are constantly changing.
