Hi I have the following code I tested to encrypt/decrypt file and all is good. It works correctly for full file encryption and now I want to test partial encryption of 100000 bytes. I tried read the 100000 from a text file full of "qwerty" text and encrypt it in another file and I am able to decrypt this file back to the 100000 bytes of "qwerty" output to a new test file.
So it seems like the partial encryption is ok, all I need is implement CipherInputStream to decrypt the first 100000 bytes write to a output file and do a normal FileInputStream and write to the output write. Theoretically I should have implemented the partial file encryption/decryption.
Now, when I open the output file, I saw unreadable character at EOL. What is wrong, how can I correct it?
EOF -> "qwertyqwertyqwertyqwertyqwertyqwerty±„w'çø]uX\œaQ2ËIõ“Ü±õþËÜTN³'"
