Any suggestions for a secure/encrypted text editor? Or some sort of encrypted container? (on Ubuntu)

Use-case: I want to make notes that are encrypted at rest on my computer. Ideally it would be encrypted in memory/swap etc. too but that's probably asking too much. Basically I don't want to have to decrypt/encrypt manually each time and don't want to run the risk of leaving non-encrypted versions lying around.
