Try encryption tools

The password you type at connect, the sealed documents, the extra layers you can inspect — they live here as interactive tools: hashing, authenticated encryption, password envelopes, a cascade of layers.

At-rest sealing, as buttons you can press.

This is how Glitr talks about at-rest sealing, not a tutorial that replaces What is encrypted vs what a host can see.

The gallery cascade can toggle a password layer. The product recipient path does not: it always runs AES → Signal → PQXDH, then RSA hybrid → ML-KEM. Password envelopes stay on your mailbox documents.

Handshake and post-quantum pieces are also on Signal and post-quantum. The shipped story is Signal Protocol and the post-quantum path.
