i am doing a project in which i simulate symmetric encryption in routers.so hav to store secret keys for mac encryption in a symmetric matrix.how do i do it?????????should i convert them to strings and then store strings in a matrix???????
okay,there is a SecretKey class in javax.crypto,i want to store a 2-D array of such keys,
like i want to declare "SecretKey key" so that key[j]=key[j] therefore the key between router-i and router-j is the same and i can perform symmetric encryption.
lets say i hav a list of routers from 0 to 7(8 routers),in a 2-D array of size 8X8 i store SecretKey's.I use symmetric encripton so if i am sending a packet from router-i to router-j at router-i i use secretkey[j] to perform encryption at router-j i perform decryption by using secretkey[j].
write a C++ program which take inputs from the user/keyboard and calculate his ZAKAT.
get the input from user may include
-Amount invested in business
-Amount given to other business partners as loan
-Amount payable to others
I made a prime number finder, it finds the nearest prime that is above and below any integer (Does not work that well with giant numbers.)
Made this in cpp.sh
Why would I need the x=y+1-1;?
x=y; just doesnt seem to work
Why is this?
And I know my coding ...
there are five tables (personTb, addressTb,churchTb) each holds data pertinent to an individual; (personAddress,personChurch) each hold the primary key for the person table and corresponding table IE personAddress holds primary key for addressTb.
both snippets work, my question is; Is my join correctly formatted?
