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.
