how to use libgcrypt library

[Zen]

Neil,

Thanks for your help.

My OS is linux.The linking proble is still not solved.I will try again.

Thanks for your advice. I have read <applied cryptography(chinese edition)>, and have put forwad a new method for multicast source authentication using encrpytion techniques in my master degree thesis. But i still can't understand libgcrypt well.Perhaps it is too complited for me.

I have just looked your homepage and photo,cool! 

Best regards,
Zen.
