Hybrid-AES-Blowfish algorithm: key exchange using neural network

Crypto-system hybrid is method using symmetrical for secure file and using symmetrical algorithm to secure key symmetrical algorithm, dependency key public for security file is one of things important for avoid occurrence attack, at this research we proposed Neural Network for composing key public that evaluated with 1000 example plaintext, based on result testing level accuracy realize 99.98%, formation of the key made as input data at AES, Blowfish, and Hybrid algorithm for secure signature file.
