So explain to us the workflow of sharing data to them

Problem: Send a file securely

Solution: Encrypt file using PortableSecret, send file over unencrypted email.

Problem: Send the decryption pasword

Solution: I can't use unencrypted email to send secrets. Let me use end-to-end encrypted Signal for that

---

What problem did you solve, that didn't complicate the process of just sending the file with Signal to begin with?

> Problem: Send the decryption pasword

I can choose a password such as 'The name of uncle Robert's favorite movie' (i.e. something that it's easy for her, but hard for everyone else).

I can call her, and say: 'Just sent you a password-protected file. The password is 'Foobar'

I can include the password in the email itself (doesn't protect from an attacker but protects from mail provider snooping/indexing emails).

It doesn't make my communications NSA proof. It adds a little bit of privacy. For the specific use-case, it's more than enough.
