Signal vs. Others
I can't find the source now but I thought I read somewhere a while back that 'those in the know about these things' didn't rate Signal too highly from a security standpoint, as it uses a "roll your own" encryption algo —which is generally considered to be a silly idea.
Same half-remembered source led me to using Wire [wire.com] when looking for an encrypted messenger as being: 1: Swiss based, 2: Uses tried & tested encryption algos, 3: Also open source
I'm not saying Wire is perfect [the mobile apps, especially, have bugs which have persisted for years] but it's pretty usable. I'm just wondering if Signal would have been a better choice?
