The Freenet Project

Compare

  Analyzed 1 day ago

Freenet is a peer-to-peer network designed to allow the distribution of information over the Internet in an efficient manner, without fear of censorship. It is completely decentralized (there is no person or computer essential to its operation), meaning that Freenet cannot be attacked like ... [More] centralized peer-to-peer systems such as Napster. Freenet also employs intelligent routing and caching to learn to route requests more efficiently, automatically mirror popular data, make network flooding almost impossible, and move data to where it is in greatest demand.

I2P

Compare

  Analyzed 1 day ago

I2P is an anonymous network, exposing a simple layer that applications can use to anonymously and securely send messages to each other. The network itself is strictly message based (ala IP), but there is a library available to allow reliable streaming communication on top of it (ala TCP). All ... [More] communication is end to end encrypted (in total there are four layers of encryption used when sending a message), and even the end points ("destinations") are cryptographic identifiers (essentially a pair of public keys).

encfs

Compare

  Analyzed about 7 hours ago

EncFS provides an encrypted filesystem in user-space. It runs without any special permissions and uses the FUSE library and Linux kernel module to provide the filesystem interface. You can find links to source and binary releases below. EncFS is open source software, licensed under the GPL. As ... [More] with most encrypted filesystems, Encfs is meant to provide security against off-line attacks; ie your notebook or backups fall into the wrong hands, etc. The way Encfs works is different from the “loopback” encrypted filesystem support built into the Linux kernel because it works on files at a time, not an entire block device. This is a big advantage in some ways, but does not come without a cost. [Less]
