# ssb_ap_bridge
A Javscript module to implement ActivityPub compatibility to [ssb](https://github.com/ssbc/ssb-db)
Feel free to open a PR or issue!
## What currently works:
- Webfinger detection of known ssb users
- logging AP messages in ssb
## What still needs work:
- Converting messages between the services
- encryption of converted messages
