kbns··on Ask HN: Why Are We Ignoring the Urgent Need for End-to-End Encrypted Emails?
While I understand the challenges with SMTP-based email, dismissing privacy concerns as ignorance is unhelpful. It's not at all a technical difficulty—Modern threats demand updated solutions, and opportunistic-TLS isn't enough. Financial incentives and data monetization do play a role in the reluctance of major providers. If new protocols can secure chat apps, similar efforts should be made for email.

Users deserve better privacy protections despite historical constraints.

Thank you. i will learn more about it.

Thank you. Since i'm using this to encrypt backups, speed is not a problem.

> multiple symmetric ciphers in sequence is still a permutation.

No its not. The data feeding to the next algorithm is an already encrypted data from the previous algorithm. Theres 0 connection b/w them.

For example . step 1 . encrypt message (M) with key (K1) using AES to produce cipher text (C1) step 2 . encrypt message C1 with key K2 using TripleDES to produce C2. step n . and so on using all algorithms with different Keys.

I don't see any connections b/w them. 0 entropy. Please correct me if i'm wrong.

"roll your own crypto" means writing a new encryption scheme. But here i'm just using multiple schemes without connection to one another by using different encryption keys.

What if AES-256 gets compromised?

Basically i'm storing my encrypted data online. Anyone can see it but only i can decrypt it.
