Unhappy working details of loopback devices

i am new to the linux environment...
currently i am working on disk encryptors..

during going through the linux i found losetup can be used in this case.
but i am not aware of its technical details. because i am involved in development of an application which involves

i) creating and managing raw partition.
ii) data should be encrypted when being written.
iii)it should be decrypted when being read.

i am using RHEL ES v4.0 and C language

can anybody help me in finding out working details( like information flow/ flowchart/intraction with different linux module) of loopback devices.

why not try crpto-devices

losetup <loop> <file>
cryptsetup <name> <loop>
use /dev/mapper/name for all purposes ... <file> will have encrypted contents !
