seppl 0.4 Description:
seppl is both a protocol definition and a software implementation of a new encryption layer for IPv4. seppl project makes use of symmetric cryptography for encrypting the whole traffic on a network. Its implementation is designed around Linux netfilter/iptables. seppl introduces two new netfilter targets: CRYPT and DECRYPT. A firewall rule may thus be used for encrypting/decrypting the incoming and outgoing network traffic. This makes seppl extraordinarily easy to use, since no daemons need to run for secure communication. seppl uses the encryption engine of the Linux Cryptographic API which is available in kernel 2.4.22 and newer.
