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.

Step 1:
Add Jason's GPG key. Jason Rhinelander, a member of the Session Technology Foundation and is the current signer for all Session Desktop 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=1.15.0
wget https://github.com/session-foundation/session-desktop/releases/download/v$SESSION_VERSION/signature.asc
Step 3:
Verify the signature of the hashes of the files.
gpg --verify signature.asc 2>&1 |grep "Good signature from"
The command above should print "Good signature from "Jason Rhinelander...
". If it does, the hashes are valid but we still have to make the sure the signed hashes match the downloaded files.
Step 4:
Make sure the two commands below return the same hash for the file you are checking. If they do, file is valid.
Linux
sha256sum session-desktop-linux-amd64-$SESSION_VERSION.deb
grep .deb signature.asc
macOS
Apple Silicon
sha256sum releases/session-desktop-mac-arm64-$SESSION_VERSION.dmg
grep .dmg signature.asc
Intel
sha256sum releases/session-desktop-mac-x64-$SESSION_VERSION.dmg
grep .dmg signature.asc
Windows
Powershell
Get-FileHash -Algorithm SHA256 session-desktop-win-x64-$SESSION_VERSION.exe # checksum is uppercase but should otherwise match
Select-String -Pattern ".exe" signature.asc
Bash
sha256sum session-desktop-win-x64-$SESSION_VERSION.exe
