     * <pre><code>
     * $ openssl enc -nosalt -aes-128-cbc -a -in input.txt -out output.txt -p
     * </code></pre>
     * The output string will print something like:
     * <pre><code>
     * key=5F4DCC3B5AA765D61D8327DEB882CF99
     * iv =2B95990A9151374ABD8FF8C5A7A0FE08
     * </code></pre>
     * Now convert the key and iv into bytearray and add to your java code. Given the above key and iv the result bytearrays will
     * be:
     * <pre><code>
     * byte[] SECRET = new byte[]{95, 77, -52, 59, 90, -89, 101, -42, 29, -125, 39, -34, -72, -126, -49, -103};
     * byte[] IV = new byte[]{43, -107, -103, 10, -111, 81, 55, 74, -67, -113, -8, -59, -89, -96, -2, 8};
     * </code></pre>
     * The key can be converted into a byte[] array using this python script:
     * <pre><code>
     * >>> s = "5F4DCC3B5AA765D61D8327DEB882CF99"
     * >>> ",".join("{:d}".format(int(s[x:x+2],16) if int(s[x:x+2],16)<128 else int(s[x:x+2],16)-256) for x in range(0,len(s),2))
     * </code></pre>
