| Encryption | The protocol uses SPAKE2 password-authenticated key exchange to establish a shared secret, and peer-to-peer traffic is encrypted with keys derived from it. | Files are encrypted on the sender's device using OpenPGP with AES-256, and a split-key design means SendSafely cannot decrypt their contents. |
| Integrations | Listed integrations include a tmux plugin for file transfers and termshark support for transferring pcap files. | Native integrations include Zendesk, Salesforce, Intercom, Freshdesk, Jira, Outlook, Gmail, Slack, Global Relay and Zapier. |
