I want to encrypt my data using the Diffie hellmen key agreement protocol. i have to implement it in java can some one help me with a example programs of how we can implement it in java

Do you actually want to secure data with it, or is this just an exercise? If you actually want security, then you should use an existing library instead of implementing it yourself. – CodesInChaos Nov 8 '12 at 11:52
ok can you give me an example of how we can do that – user1209 Nov 8 '12 at 12:16
First off, you don't encrypt with Diffie-Hellman. You exchange a key with Diffie-Hellman which can then be used for encryption using say AES or some other symmetric cipher. So, what exactly are you trying to implement? Are you trying to implement Diffie-Hellman or a program that uses a DH library to do key exchange and an AES library to do the encryption? – mikeazo♦ Nov 8 '12 at 12:25
i am trying to generate keys using DH with AES algorithm to encrypt the data can you help with a example – user1209 Nov 8 '12 at 12:41
you cannot generate keys using DH, and correct your question, using DH you cannot encrypt data using key agreement protocol, read about it first , rather than asking arbitrarily. If you are looking for quick code for something which you don't know what it should do this is not the place – sashank Nov 8 '12 at 19:12
