A libpurple/Pidgin plugin for signald (signal, formerly textsecure).

signald is written by Finn Herzfeld.

An unofficial IRC channel exists on Libera.chat called ##purple-signald for those who use it.

Known Issues

Attention: As of September 2021, this plug-in is falling apart. I am annoyed by the number of protocol and API changes and I lack motivation keeping up with them.

If notifications for group chats are enabled, the colors of sender names will differ from those in the member list, see #69.

When used with Pidgin, the user must never close a group conversation window or incoming messages will get lost. Deferred messages (sent by others while offline) will always get lost.

Getting Started

Security Considerations

UUIDs are used for local file access. If someone manages to forge UUIDs, bypassing all checks in Signal and signald, the wrong local files might be accessed, but I do not see that happening realistically.
