Possible encoding type to convert a byte array to be sent by SMS -

-

I have to send a public key made by RSA via SMS to any other phone. I am converting 148 bytes of public key into base64 to be sent by SMS.

As if byte [] can not be sent directly by SMS, what are the other possible ways to successfully convert the string or the equivalent, which can be sent through SMS? Besides compacting, is Base 64 the only possible way?

You can SMS one in 8 bit mode - most GSM modem and gateway have this option , And some phones expose this capability in their APIs too.

In this way you can send the whole key, and still 12 bytes for additional data. You'll need some software on the phone that will be able to read and use the message, though.

Another option: send it to two different related SMSs; The most (?) Phone is to add a different message and to add a logical message (to understand how it works, you will dig into SMS protocol specifications).

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
