Java AES implementation

This is a little Project, I had. This here is a simple implementation of the AES Algorythm based on the one from Rijndael. At the moment, it can de- and encrypt files.

Usage

If you only want to encrypt:
[name] inputfile
Then the key will be stored as inputfile.aeskey and the outputfile will be stored as inputfile.enc

For encryption with a specific key
[name] -i inputfile -k keyfile -e
Then the output will be stored as inputfile.enc

For the decryption
[name] -i inputfile -k keyfile -d
Here the file to output will be stored (as not other mentioned) as inputfile minus the last 4 characters (default without .enc)

All arguments:

-i inputfile        File for input
-h                  Display the help  
-o output           File for output  
-k keyfile          File of the key  
-v [optional] mode  Enable the verbose mode  
-p                  Enable the percentag mode to display the percent finished (May spam some command promts)  
-e or -d            Encryption or decryption mode  
-p                  Enable the percentage mode to display percent (Slows down encryption)
