Help needed in choosing an algorithm for Cryptographic services.

[abhishek]

Hi group, recently my employer asked me too implement encryption/
decryption for secure data transfer over internet. Problem is that the
client application is written using C# and the webserver where i need
to store the information is developed using python.

My situation of dilemma is which cryptographic method suits me best
for this purpose.

Help/Suggestions are urgently required

Thank you ,
Abhishek
