# * Description: This simple program makes brute force into a gpg file 
# * using a password dictionary generating a decrypted output file.
# *********************************************************************************
# * For use this version was necessary breaking rockyou.txt in parts of 4Gb with
# * the command: split -l 4000000 -d rockyou.txt rockyoup  
# * and was generated files like rockyoup01, rockyoup02, rockyoup03,...
# *********************************************************************************
# * Example: $ ./decgpg myfile.gpg myfileout.txt /usr/share/wordlists/rockyoup01
# *********************************************************************************
