cpdu is a command-line file encryption tool for Linux/UNIX that allows for storing encrypted files into archives. It uses secure memory allocation and allows for a secure local key file securely stored into your home directory
It has more room for improvement and in the future will allow transferring encrypted files over the internet using a server and client implementation, the tar file has bcp(brutal oopy) along with it so you can use that for now to transfer encrypted files however no public key implementation has been added so there must be an high level key transfer method.
