comment Where to store the file extension to retrieve it correctly after decryption
If you don't need to keep the extension secret, the obvious alternative would be to keep that as a part of the filename. For example, you might encrypt the file 'test.pdf' as 'test.pdf.encrypt'.

comment homomorphic paillier cryptosystem vs Elliptic curve cryptosystem
@Vrundapatel: what form of ECC encryption has homomorphic properties. For example, with EC ElGamal, what operation can you do on two encrypted values which results in an encryption of some nontrivial function of the two plaintexts?

comment homomorphic paillier cryptosystem vs Elliptic curve cryptosystem
@Vrundapatel: if you do need the homomorphic properties of Paillier, then why does it matter how much faster ECC is? After all, ECC doesn't meet your requirements; it doesn't matter how much faster it is.
