Hi

I have a Java web service and a Java web client making use of this service. One of the functions is to create a new user account. My two concerns are:

How will I send the user's password securely from the client.
How will I store the user's password securely on the server.

How can I achieve these? I know the theory basically behind security, security algorithms etc but can anyone give me some advice on how I should go about in coding? Could anyone point me to some good (and if possible not complicated) examples to follow since I found some examples on the Internet very contorted?

Thanks a lot and regards, Krt_Malta
