Session Android

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:

Add Jason's GPG key. Jason Rhinelander, a member of the Session Technology Foundation and is the current signer for all Session Android releases. His GPG key can be found on his GitHub and other sources.

wget https://github.com/jagerman.gpg
gpg --import jagerman.gpg

Step 2:

Get the signed hashes for this release. SESSION_VERSION needs to be updated for the release you want to verify.

export SESSION_VERSION=1.20.8
wget https://github.com/session-foundation/session-android/releases/download/$SESSION_VERSION/signature.asc

Step 3:

Verify the signature of the hashes of the files.

gpg --verify signature.asc 2>&1 |grep "Good signature from"

The command above should print "Good signature from "Jason Rhinelander...". If it does, the hashes are valid but we still have to make the sure the signed hashes match the downloaded files.

Step 4:

Make sure the two commands below return the same hash for the file you are checking. If they do, file is valid.

sha256sum session-$SESSION_VERSION-universal.apk
grep universal.apk signature.asc
