Mr.D.RAMANJANEYULU@ramu , FACULTY, JIT,JU, offering course B.TECH FINAL YEAR CSE , COMPUTER SECURITY , computer security, network security and cryptography, information security, information assurance and security,cyber security all are under same umberalla.

is it possible to understand in the first 3pages what i wrote?

definitely no, only source (who wrote), destination (whom it wrote for) these two parties only will get understand

only 2 persons will get the information and use, rest of the world will see but no use for them, they can’t benefit by any means

this is the essence what the all the courses offers 

the above 3 pages contains unit-1 for B.Tech, my hand written script various cryptography technics 

4th year 1st semester, testimonial is the 4th screen, authoritatively  , foreign university 

COMPUTER SECURITY(JU.JIT) ,
