Hello students we need we are asking the question suppose the rac crypto system is used with public key public key is given 35 so public key is given as 35 comma 7 and we are asked that what is the corresponding cipher text when plain text 2 is sent right so here e value is given as 7 and if i write for this n value is given as 35 so let's start with our answer and h value is given, so plain text h value is given us 2.
00:37
So we can write here if plain text for plain text, if i write for this, h is less than n where 2 is less than 35 which is true.
00:49
So we can write here, we can write here, cypher text would be then cipher, if i write here for this, then cipher text would be.
01:07
E is equal to h -raged 2 power i and modulus, modulo with, if i write here for this, with n.
01:18
So let's start with our answer, we need to find that.
01:23
So this is, and for cyper test, we need to symbolize this by c.
01:31
So let's start with our answer...
