Hi,
tell me the best algorithm for encryption
I want to encrypt sms of my mobile as it is part of my project.
I am going to use public-private key techniqe....tell me for that which will be the best algorithm.

As I want to encrypt the message for which I will create a one jar file so it can run on any java mobile.

At the end of the day, the exact choice of algorithm is down to you.

First you will need to look at the Java Encryption names spaces to see which asymmetric algo's it supports.
You will then need to look at each of those to ensure it is supported on your chosen platform.
You will then need to look at each and see whay +/-'s exist, e.g. speed, key lengths, rounds, etc. etc.

Then go test them to see which one work well on a mobile given its memory and processor speed.
