java.lang.ArrayIndexOutOfBoundsException: too much data for RSA block

Question

I\'m using RSA encrypt text and decrypt text. The public key and the private key are generated with openssl tool. I encountered an \"java.lang.ArrayIndexOutOfBoundsException

Answer 1

Fianlly I modified my codes like that and they work well:

    public static String encryptData(String text, String pub_key) {
        try {
            byte[] data = text.getBytes("utf-8");
            PublicKey publicKey = getPublicKey(Base64.decode(pub_key.getBytes("utf-8"), Base64.DEFAULT));
            Cipher cipher = Cipher.getInstance(RSA);
            cipher.init(Cipher.ENCRYPT_MODE, publicKey);
            return Base64.encodeToString(cipher.doFinal(data),Base64.DEFAULT);
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }
    public static String decryptData(String text, String pri_key) {
        try {
            byte[] data =Base64.decode(text,Base64.DEFAULT);
            PrivateKey privateKey = getPrivateKey(Base64.decode(pri_key.getBytes("utf-8"),Base64.DEFAULT));

            Cipher cipher = Cipher.getInstance(RSA);
            cipher.init(Cipher.DECRYPT_MODE, privateKey);
            return new String(cipher.doFinal(data),"utf-8");
        } catch (Exception e) {
            return null;
        }
    }

If something seems wrong still you can remind me. Thanks for James and Henry's answer.
