Java RSA Public Key from String Error

Question

I'm trying to convert a string to RSA public key, but I always get errors... Public Key:

The code:

pub.replace("-----BEGIN PUBLIC KEY-----\n", "").replace("-----END PUBLIC KEY-----", "");
        byte[] publicByte = Base64.getDecoder().decode(pub);
        System.out.println(publicByte.length+"deb");

        X509EncodedKeySpec keySpec = new X509EncodedKeySpec(publicByte);
        KeyFactory keyFactory = KeyFactory.getInstance("RSA");

        PublicKey pkey = keyFactory.generatePublic(keySpec);

Error:

java.lang.IllegalArgumentException: Illegal base64 character 2d

I would be happy for any help.

0x2d is -. The hyphens etc. are still there. String.replace() returns the new value. It doesn't mutate the string you called it on.
