Base Convert and Base Encode

Base Convert

Base conversion is a very basic skill in programming.
I was taught converting between decimal(base-10) and binary(base-2), decimal(base-10) and octal(base-8), decimal(base-10) and hexadecimal(base-16), and of course among base 2-powered numbers(pow(2,n)).

The conversion is quite simple, division is the only arithmetic operation we need.
If we want to convert a base-m number to a base-n number by our hands, the common way is:
1 Convert base-m number A to base-10 number B;
2 Convert base-10 number B to base-n number C.

I created a pull request here, but seems IntrepidusGroup guys are not working on this anymore.

And the TCP/UDP raw protocol debug still not work for me. Hope I can figure it out one day.

Btw, quotes of my commit logs:

Brief Intro to Mallory

MiTM(Man in The Middle) is a good way analysing protocols, especially when there’s an SSL.
To analyse HTTP/HTTPS protocol, we have Charles Proxy. Posts on my blog can be found (there’s another MiTM proxy, ‘mitmproxy’, and, will try later.)
For others, mallory is recommended.


Mallory is an extensible TCP/UDP man in the middle proxy that is designed to be run as a gateway. Unlike other tools of its kind, Mallory supports modifying non-standard protocols on the fly.

We have mallory from and
