Document encryption and decryption

A computer-implemented method of creating encryption and decryption of a computer file in a computer comprising the steps of:

• assigning a key to a user, where the key is utilizable with at least more than one file or item;
• retrieving and transmitting identification of said computer automatically upon said computer connecting to a network to at least one remote server;
• comparing said computer identification with stored credentials identified for remote deletion for selectively deleting at least encrypted files from said computer if tagged for remote deletion;
• receiving a request from a user that an action be performed to at least one item on a computer;
• transmitting user credentials to said at least one remote server inputted by said user;
• comparing said user credentials with stored credentials at said at least one remote server for authenticating said credentials associated with said user for controlling user requested access;
• accessing said key where accessing said key comprises first said user sending an invitation, where said invitation is processed via asynchronous electronic mail service to improve performance, to a second user using said at least one remote server, and said second user accepting the invitation resulting in said user and second user being linked establishing a one-on-one relationship between these two parties;
• applying said key assigned to said user that is unique to said user and stored on said remote server;
• processing and performing said requested action of said authenticated user;
• and wherein
• asynchronous electronic mail service processing is via validated connections to database queues based on wait times.
