Hello @john_tedesco. Thanks for the follow. I guess you found me through some Mastodon mass-following tool while you were searching for people in Information Security / Hacking.
Reading your contact page https://johntedesco.net/blog/contact/, have you considered...?:
1 - Signal. End to end encrypted, FOSS and only requires a phone number.
2 - Threema. Audited, Swiss-made, closed source, single payment application.
3 - Keybase/traditional PGP/GPG.
Let me know if you need help setting any of those up.
Thanks. I'm on Signal and Keybase, but not a whole lot of people I know use Keybase. I had not heard of that other tool, will check it out.
@john_tedesco I'm not sure if you're aware, but being on Keybase means you can also offer your PGP/GPG key to anyone who uses it. For example, for me, in the screenshot, it appears below the "5 devices" link.
PGP/GPG is the form of encryption ProtonMail uses, so it is well industry-tested.
Threema is not widely used because it costs money. But if you decide on buying it and want to test it with someone, let me know and I'll give you my Threema ID.
