Java remove public key header and footer from string

Question

Hi I am trying to remove the header and footer off a public key that is being stored as a string. I have managed to work out how to remove the "begin" header by removing everything up to the first "\n",

-----BEGIN PUBLIC KEY-----\n

with this code.

String s1 = pKey.substring(pKey.indexOf("\n")+1);

I am however struggling to remove the footer from the end up to the last "\n".

\n-----END PUBLIC KEY-----

There must be a cleaner way to remove them both.

Answer 1

Public key can be Some thing like this "-----BEGIN PUBLIC KEY----\nkey\n-----END PUBLIC KEY-----"

So to remove header and footer from string you can use pKey.substring(pKey.indexOf("\n")+1, pKey.lastIndexOf("\n"));

or other way just replace header and footer directly by empty , since it won't be present in key
