comment Is AES really used for Top Secret stuff?
Although I'm not a mathematician, I think it's fair to say not all keys are created equally. That being said, I'm sure they do something to discern weak(er) keys from strong(er) keys.

comment Is AES really used for Top Secret stuff?
Well there are different modes of AES as I'm sure you know, like GCM, which are better than others. Also when working with encryption systems and not just algorithms, you have to worry about buffer overflows caused by viruses to steal encryption keys and even accidental RF emission of plaintext. This actually happened with a Soviet encryption machine - if you listened into the background, you could actually hear the plaintext because the wires weren't properly insulated.

comment File encryption with one keypair?
I understand the risks with say temporary files being written to the disk and keys staying the in the RAM, especially in a high-level language as Java or C#. Basically I'm trying to implement NSA Suite B encryption for a personal project, not really to protect anything valuable. All the ZIPing and stuff is just to keep the required parts of the encryption together.

comment File encryption with one keypair?
Looking through the specs on the algorithm, there is a message to be encrypted and decrypted so that wouldn't be the entire file but rather the regular symmetric AES key for encrypting the file, correct? In other words, the ECIES scheme only protects the key for regular AES file encryption?
