High level text encryption program (symmetrical encryption). Processes text files only and there is no GUI interface encryption and de-encryption is done from the dos command line. Based on old but highly effective encryption technology. The actual code used to create this version of the program was destroyed. Keys are 2-40 in number. Program has been around since 2002 and has a relatively small number of users, all of whom are satisfied. This is not a plaything it is for grown-ups.
