How to recover a RSA public key from a byte[] array?

Question

Hello, I'm wondering if it's possible to recover a RSA public key that I have converted to byte array previously.

byte[] keyBytes = publicKey.getEncoded();

Thanks for the help.

Answer 1

PublicKey publicKey = 
    KeyFactory.getInstance("RSA").generatePublic(new X509EncodedKeySpec(bytes));
