i used both the hashkey generation process using app and using linux terminal. but they are giving me different hashkeys , the one i get using JAVA code, if i want to add that hashkey, then it cant be added, linked in says hashkey is malformed,on the other hand the one I get from console, it can be added, but if i add this, then I get the above mentioned error while authenticating. Please help me out.

Eventually, I got managed to solve my problem, what I did was used both keys, after that I did not incur any more problem
