i would like to ask about:
What is the difference between Authenticated Encryption Modes and Generic Composition Schemes in cryptography?
Thanks
Generic Composition Scheme basically tells you take some proven cipher and some proven MAC function, use the cipher for encryption and the MAC for integrity in some way and hope for the best.
Authenticated encryption modes are basically the same thing, just some cipher with a MAC function, but usually those where checked and have provable security. Such as GCM is a combination of CTR mode with GMAC, or CCM that uses CTR mode with CBC-MAC. Or using AES-CBC with HMAC.

Someone please state two or three applications of RSA algorithm. I heard that RSA is used for SSL. Is that true?
Yes, that is true. RSA is an encryption algorithm.
Example uses:
SSL
SSH
Digital signatures
PGP
RSA is used in cryptography in Key-based authentication.SSH uses this method of key generation as it is considered very secure.

What language can you recommend (and why) for making networking tools:
network analyzer (packet sniffing)
speedtest (sending traffic, calculating the total speed and involving QoS analyses)
network monitor (promiscious mode network listener)
SSH client (with own extensions)
I'm thinking about: Java, C# or C++ (reason: Object oriented, found some standard functions in the language itself without having to import existing api's)
The purpose is to learn to write such apps without the use of API's.
I would use an unmanaged language for the sensitive parts of the apps. Anything where latency and absolute performance are an issue. I'd use Java or a managed .Net language for everything else.

If somebody writes a web server in a programming language, a server that listens on a socket (e.g. 80) and serves files with headers. What are the first threats it can experience once it goes out in the wild?
I would imagine that hackers will start with a buffer overflow attack. They could do things like call URLs that are too long or request headers that have malformed components.

i need some tutorial links that describes the creation of generic provisiong profile for development or distribution.
thanks for any help.

If you mean a provisioning profile that can be used across a suite of applications what you need to do is create a wildcard app id.
However, there are some limitations to using wildcards such as not being able to use gamecenter functionality.

Is anyone aware of a plugable Email Templating solution for C#? I've grown weary of having to roll my own each project and I imagine there are more robust solutions out there. It should support HTML/non-HTML and allow for tokens (e.g. USERNAME is replaced with a configurable value).
ComponentForge Mail Merge Suite is a
set of flexible and easy-to-use .NET
components for generating dynamic
email content with DynamicTemplate.

If you're looking for a free hack, OpenOffice claims to be capable of this:
