sup. is an open source encrypted fediverse instant messenger, similar to whatsapp, made by pixelfed.
The beta will be launching later this month, and btw most fediverse accounts will work, not just Pixelfed
@dansup will it use the Signal protocol?
@fishidwardrobe I don't think there's any requirement for phone numbers in the #Signal Protocol.
They all sound similar but the Signal Protocol (the technical spec; also used by WhatsApp), The Signal Foundation (the non-profit entity behind Signal), and Signal (the messaging service) are all different things.
@fishidwardrobe@mastodon.me.uk @dansup@mastodon.social @Yuvalne@433.world no, my guess is that it'll use the encryption standards provided by libsignal without using signal's services.
@kainoa@firefish.social @fishidwardrobe@mastodon.me.uk @dansup@mastodon.social @Yuvalne@433.world so, axolotl encryption, also known as signal/whatsapp/matrix/omemo(xmpp) encryption
@fishidwardrobe @dansup @Yuvalne No, it's used in Skype as well where you're not forced to link it.
Please consider MLS, end-to-end encryption protocol standardized by IETF: https://blog.phnx.im/rfc-9420-mls/
Matrix and some other messengers are going to adopt it, so there's a possibility that we can interoperate with them in the future.
