In 2023, Signal was the first mainstream messenger to enable post-quantum cryptography. We’re still ahead of the (elliptical) curve, implementing a new hybrid PQ ratchet ensuring Forward Secrecy & Post-Compromise Security even in a post-quantum world. https://signal.org/blog/spqr/

@signalapp I love this but, despite my two Masters' degrees in English, I don't understand it - which probably goes a long way in accounting for why I love it

encryption depends upon basically really hard math problems to work
this has worked well for a long time
but now we have quantum computing
while it is in its infancy it makes really hard math problems really easy
so that means in some time, encryption will stop working (all banking and finance, all military comms, etc: it can be hacked)
luckily there are encryption schemes that are resistant to quantum computing
but they have to be implemented
#Signal implemented it

@benroyce @erikcats @signalapp For the record, we do not have quantum computers yet, nor do we know when or even if we'll have them for any outside-the-lab purposes.
Good encryption is never a bad idea though
