Python RSA implementation with PKCS1

[jiee]

I'm working on this Python package for RSA implementation <link removed>,However,It only gives a RSA implementation without PKCS1 padding.

I'm now trying to improve the code snippets for PKCS1 padding. I followed the RFC2313 http://www.faqs.org/rfcs/rfc2313.html and get a list object like this:

m = [0,2,random integers,0, integers]

According to RFC2313, the list above is to be transformed into "an integer in big-endian form", and the following equation was given:


x = SUM 2^(8(len(k)-i)) m[i] .

I was confused about how to transform the list object into "an integer in bigendian form". Any snippets written in Python would solve this problem?

Any help would be appreciated.
