I encrypted a message by:

  1. Typing gpg --encrypt --armor --recipient [recipient]
  2. Hitting enter
  3. Typing the message to be encrypted
  4. Exiting/finishing with “ctrl + d”

However, I needed to press “ctrl + d” twice, for some reason. Maybe a Termux bug? Although I haven’t tried it on a normal Linux distro, so maybe this is normal?

Question: if it isn’t normal, did gpg encode/include the first “ctrld” in the encrypted message? If it did, I need to contact the recipient to tell them to disregard the message… 🤣

Naturally, I cannot reverse the message since it’s encrypted with the recipient’s public key.

    It doesn’t improve any guarantees, it’s strictly an opsec practice. By default you can publicly view the fingerprint of the public key(s) of the recipient(s) to aid in selecting the correct key for decryption, while --throw-keyids removes that metadata. Don’t use it if you want to demonstrate that the message is not additionally encrypted to other keys, i.e. the conversation is confidential. Use it if you don’t want a MitM to know who you’re talking with.
