I wonder if there's any way that the hash of a cipher text can be taken since hashes are not invertible (but encryption is).
Feels like it would be a really good idea to encrypt a hashed output (specifically ; not signatures though).
I only say what I said above because if the hash is being used to obfuscate / hide something, then the encryption will ensure that in the worst case scenario, someone will only find a hashed out / mixed version of what they're to decipher (and there's a considerable burden to be able to get to that point).
Need to Definitely Test for the AEAD Quality of This (perhaps if the hash was encrypted with XChacha20 - poly1305?)
Thinking that there's some version of this idea that ties into what I was thinking as it pertains to hash chains.

Secure video calling is in high demand. As an alternative to Zoom, many people are using end-to-end encrypted apps such as WhatsApp, FaceTime or Signal to speak to friends and family face-to-face since coronavirus lockdowns started to take place across the world. There’s another option—secure communications app Telegram just added video calling to its feature set, available on both iOS and Android. The new feature is also super secure—like Signal and WhatsApp and unlike Zoom (yet), video calls will be end-to-end encrypted.
Telegram Auto-Delete Messages in Any Chat
Some messages aren’t supposed to last forever. There are some Telegram groups and conversations where it’s best if messages are automatically deleted in a day or a week. Here’s how to auto-delete messages in any Telegram chat. You can enable the auto-delete feature on a per-chat basis. It works for both one-on-one conversations and group chats. Previously, you needed to use the Secret Chat feature to automatically delete messages after a set time. At the time of writing, you can choose to automatically delete messages after a day or a week. Telegram starts the timer once they are sent, not after they are read. This won’t affect the messages that were sent before enabling the feature.
