Abstract: The rapid growth of internet and networks applications has given rise to many data security issues. Encryption algorithm plays a crucial role in information security systems. This paper presents the hybrid encryption scheme which combines the fast encryption speed of symmetric algorithm (Blowfish) with the security of asymmetric cipher algorithm (SRNN). The proposed approach includes file splitting and merging mechanism along with hybrid encryption where each slice is encrypted by its corresponding key.

Keywords: Hybrid cryptosystem, File Splitting, SRNN, RSA, Blowfish.
