Maybe try accepting answers for your past questions then someone will probably answer this one too.

I think that I have a pretty low accept rate (3 questions/1 answer), but I haven't gotten an acceptable answer for some of the questions. It looks like OP might be taking it a little far, but if it's a useful question we might as well answer it.

The iPhone SDK includes the Security Framework, this library includes many common crypto functions.
If you're a little more specific I can help you out with a high level implementation.

Kindly help me for some specific algorithm which I can implement at both php and objective c end.

Could you let me know at least the nature of the encryption, will you just want to protect something during transport? Do you want to store some encrypted data in a database?

Actually I am sending the sound data from iphone, which is receive on web server. PHP script save the sound in to some specific directory. Now I want to encrypt the sound at iPhone end and Decrypt at php end, after decryption it store into some specific directory. I have already implemented the AES-128 bit encryption algorithm, but I am not be able to get the specific result. Kindly help me.

Sounds like you just need encryption during transit, if that's the case I would recommend just using HTTPS(SSL). You'll need a certificate for your site, but I believe that those are reasonably priced now.If this is not an app that you're selling you *can* install a certificate to your iPhone/iPod Touch by e-mailing it to yourself then opening it from the Mail app.If you'd really rather use AES128 then I'd recommend either implementing a key-exchange(more secure), or storing a key file on the device and the web server(less secure).http://en.wikipedia.org/wiki/Diffie–Hellman_key_exchange
