This is a secret key cryptographic system (or symmetric system). The secret key is communicate to the receiver by the asymmetric system called RSA (public key system). The advantages of the Bercode is very quickly rate of encrypt and decrypt, and the same plain text can be encrypt in different ways also using the same secret key.
This characteristic offers an advantage that can be obtain using a one pad system only. Moreover, the Bercode is able to encrypt files of every dimension and kind. We want to add that this is a demo version.
