Is Additive Cipher / Caesar Cipher / Shift Cipher are same

yesh dea

C= 4+ 15 mod 26 = answer should be 7 right ?? Correct me if i am wrong !

[@LastNightStudy1903]

(4+15)mod 26
will be 19 mod 26
now becausw 19 is smaller than 26 ...the remainder will remain 19 itself... so answer is 19 [your final answer will be 19]....
on other side lets take example c=36 mod 26 the it would be 10 remainder ...

[@marklouiscornea134]

is the key always 15 in additive cypher?

[@LastNightStudy1903]

no it will be provided to you in question....it can be any single number like 10,15,20,26 any...

how you fine the Key

[@LastNightStudy1903]

key will be provided without key how can you encrypt using any cipher... key is provided in question itself...

[@treramine2478]

jiss, 3:23 , just do 29-26 remainder is 3

[@LastNightStudy1903]

i intentionally did it because its something we know the answer right but calculating mod with big number becomes tough so i taught how to calculate mod of even big numbers easily with the help of calculator because there you can't minus right...it will be tough...and if i had taken big values straight away then many would have problem in understanding how am taking out mod...i hope you got it bro...the idea was to teach how to calculate mod through calculator...
