Cryptology involves both a fields of cryptography and cryptanalysis. Computer cryptography is aslo called bitstream cryptanalysis. A operations of all a algorithmic rule within computer cryptanalysis or even bitstream cryptography come according to the basic unit of bitstream. Meanwhile a bitstream consists of the binary bits of bit zero "0" & bit of these "1".

For person-depending cryptanalysis, these are of these-symbol-numbers of-meaning; whereas these are a single-symbol-a single-meaning for computer cryptography. Hence, no of these-way work in the computer cryptography, which is according to mathematical manipulation of bitstream. What is more, a being of mighty computer occurs as must for man to decrypt and/or to decode bitstream messages manufactured from either complex mathematical algorithmic program.

Then again, a polysemy and multimedia paradox features of individual-depending cryptography has caused a unbreakable situation by any cryptanalytical techniques for the messages encrypted and/or encoded under the human-depending cryptanalytics. E.g., biometrics-based cryptology, language-depending cryptanalysis, event-depending cryptanalysis & image-based cryptanalysis (or even visual cryptography) are among a couple examples of man-depending cryptanalysis. This is the major difference of machine language & mortal language.

A recent event of Hurricane Katrina a wind tragedy may propose a requisite require for mortal-depending cryptanalysis across the computer cryptanalysis. Individual-depending cryptanalysis may be utilized under the virtually all critical situation whereas computer cryptanalytics might ask for low-priced computing power of a computer. A computer cryptanalytics is fast & big for the speed and coverage severally every bit in comparison person-depending cryptanalysis. Even so, sufficient electricity power supply is the bottleneck for computer cryptanalytics. Hence these are proposed to keep close at h& two a computer cryptanalysis and man-depending cryptanalysis to become utilized together. Notwithstanding, for a virtually all critical situation, these are proposed to use person-depending cryptanalysis when the final measure.
