Summary
Session integrates directly with Oxen Service Nodes, which are a set of distributed, decentralized and Sybil resistant nodes. Service Nodes act as servers which store messages offline, and a set of nodes which allow for onion routing functionality obfuscating users' IP addresses. For a full understanding of how Session works, read the Session Whitepaper.

Verifying signatures
Step 1:
wget https://raw.githubusercontent.com/oxen-io/oxen-core/master/utils/gpg_keys/KeeJef.asc
gpg --import KeeJef.asc
Step 2:
Get the signed hash for this release. SESSION_VERSION
needs to be updated for the release you want to verify.
export SESSION_VERSION=1.10.4
wget https://github.com/oxen-io/session-android/releases/download/$SESSION_VERSION/signatures.asc
Step 3:
Verify the signature of the hashes of the files.
gpg --verify signatures.asc 2>&1 |grep "Good signature from"
The command above should print "Good signature from "Kee Jefferys...
". If it does, the hashes are valid but we still have to make the sure the signed hashes matches the downloaded files.
Step 4:
Make sure the two commands below returns the same hash. If they do, files are valid.
sha256sum session-$SESSION_VERSION-universal.apk
grep universal.apk signatures.asc
