- anotherhue 6y agoa) I feel Google is over-represented in our tech lives, so when it's possible to use an alternative I choose to. b) GCM undoubtedly collects metadata about my usage of it c) [falsified] AFAIK GCM requires a Google account, which means your usage of the system is at the pleasure of Google, and can be disabled for a myriad of Orwellian reasons.
- chopin 6y agoI use Signal on Android and I definitely have no Google account. It seems to be an optional component of Signal. As well I never was asked sign up anywhere.
- qqqqqqqqqqqqqqw 6y agoThanks for explaining. Though, like xenocratus, I thought you meant Galois/Counter Mode and was similarly puzzled :)
- lxgr 6y ago> AFAIK GCM requires a Google account It does not.
- xenocratus 6y agoI had the same question until I realised it meant Google Cloud Messaging (or, this is how people seem to interpret it) - my initial thought was that it was about Galois Counter Mode (an authenticated encryption mode), and was curious why not using it was considered a benefit. Threema does seem to use XSalsa20 + Poly1305 for authenticated encryption (not AES in GCM), btw.
- anotherhue 6y agoHaha, I'm sorry about that confusion, as a fellow crypto-fan I should have noticed.
