Change $HOME, encrypt entire Home and copying the key from the server log

[leonv024]

"...However I found a couple of issues:

1. When you set the working directory as $HOME, the encryption doesn't work. I replaced it with /home/volston and it worked
2. A cool feature to have - Is there a way to encrypt all the files in the working directly, cuz currently it only encrypts the dir. mentioned as the target directory, if nothing is mentioned, the encryption doesn't work
3. This is a stupid one but you can't copy the key from the server window with Ctrl+C or Ctrl+Shift_C. I had to manually type it in."
