If you need secure 1:1 chat, #XMPP-#OMEMO is the way to go. You could even use something like #DeltaChat which is based on PGP/MIME-eMail and allows you to keep stuff #E2EE - encrypted yet also save a history which you'll get sync'd across devices.

Remember: #NotYourKeys = #NotYourControl = #NotSecure!
#notSecure #notyourcontrol #notyourkeys #e2ee #DeltaChat #omemo #XMPP
Don't even trust me!
Use #XMPP-#OMEMO & #PGP/MIME because #NotYourKeys = #NotSecure!
Only #SelfCustody of #PrivateKeys allows full control.

And also a reminder that md5 (and other weak algorithm) hashing and hashing without salting will be here forever 🙄
