Java asymmetric encryption: preferred way to store public/private keys

Question

This code generates a pair of public/private keys:

KeyPairGenerator keyGen = KeyPairGenerator.getInstance(\"RSA\");
keyGen.initialize(1024);
KeyPair keypair = ke         


        

Answer 1

If you want to define a format for storing the keys, then I would choose a format that is expendable so that it doesn't break when you want to change encryption (when the old one gets to weak for example).

So i would store the bytes encoded as base64, together with a string that describes the format, "rsa" maybe.
