Fix

public static byte[] getKey(String key) throws Exception {
        return Base64.decodeBase64(key.getBytes("UTF-8"));//OK
        // error return Base64.decodeBase64(key);
    }

public static String encrypt(String data, String key) throws Exception {
        return StringUtils.newStringUsAscii(Base64.encodeBase64(encrypt(data.getBytes("UTF-8"), getKey(key))));//OK
        //error return Base64.encodeBase64String(encrypt(data.getBytes("UTF-8"), getKey(key)));
    }
