Document encryption and decryption

A computer-implemented method of creating encryption and decryption of a file in a computing device, said computer-implemented method comprising steps of:

• receiving a request from a user that an action be performed on a first computer;
• identifying said action requested by said user as encryption, decryption and/or opening of said file;
• retrieving user credentials and computing device identification of said first computer;
• transmitting said user credentials and said computing device identification for remote authentication of user access;
• comparing said user credentials and said computing device identification with stored credentials at a remote server component for authenticating said user credentials, and matching said user credentials and said computing device identification with said stored credentials at said remote server component;
• determining said user as authenticated;
• if said user is authenticated, applying an encryption key assigned to said authenticated user that is unique to said user and stored on said remote server component;
• processing said request of said authenticated user;
• and
• providing access to said authenticated user for a predetermined period of time to selectively proceed with requesting additional action(s) to be performed;
• wherein said method further comprises controlling remote deletion of said file, wherein said remote deletion comprises,
• receiving a user request to mark said computing device as compromised;
• storing identification of said computing device;
• generating a list of directories containing files for remote deletion;
• terminating access to remotely authenticate said identification of said computing device;
• retrieving said identification of said computing device automatically upon said computing device connecting to a network;
• comparing said identification of said computing device with said stored credentials on said remote server component;
• determining said computing device as compromised;
• marking said computing device as compromised;
• controlling remote deletion of all encrypted files and said list of directories containing files upon said compromised computing device connecting to said network;
• and
• reporting deletion of all encrypted files and said list of directories containing files as deleted.
