I am working on the DES (Data Encryption Standard ) algorithm in Cryptography as a part of which I have to write a 'C' code in linux that splits the DES key into two halves as per initial permutation of the DES key.
I need to use a function to do so. I don't know how to go about writing a code since I am new to the Linux Environment.
Can anyone help me in developing the code for the problem ?
