    Hello,
    could someone please tell me the principle and actual method behind encrypting a data?

    Data encryption uses mathematical calculations and algorithms to transform plaintext into cyphertext which is not human readable and it is also protected from unauthorized parties. The recipient of the encrypted message uses a key which triggers the algorithm to decrypt the data - back to plain text.
    Even the modern browsers encrypt data to send to secure servers so that intruders cant read after intercepting it.
    Mainly there are two broad categories - symmetric and assymetric. in symmetric encryption, one key is shared between sender and receiver while in assymetric, there is a pair of public and private keys.
    Encryption is a complete subject - (CEans from Computer Sc background must have read cryptography). If you still have queries and specific questions or want to know more, let me know.

    well, i belong to the electronics dept.. 😀

    i read a novel in which it says that it is possible to encrypt a "set of data" within a picture.. Is this just a fiction or is it a real concept??? i tried googling it, but it seems to be all cramped up..

    yes you can hide encrypted data within a picture.

    it is known as steganography.

    Ya that is true. We can encrypt the data in the form of picture. And we can even hide the data and tht study is called Staganography.
