Share (P2P)
"Share" uses encryption to hide the identity of who is transferring or what they are transferring. It is non-centralized so it cannot be easily shut down and it supports multiple source "swarm" downloading. All files are transferred encrypted so they must be decrypted upon download completion. In the meantime they are stored in encrypted form in a "Cache" folder. This folder is also used to allow recently downloaded files to be shared among the network based on priorities.
Crypto-shredding
Getting rid of data at rest like old backup tapes, data stored in the cloud, computers, phones, and multi-function printers can be challenging when confidentiality of information is of concern; when encryption is in place it allows for smooth disposal of data. Confidentiality and privacy are big drivers of encryption.
