steps:

• encrypt(by recipient public key)
• sign(by sender private key, you can sign an unencrupted message, will verfiy the sender, but your text is unencrypted e.g sign-but-not-encrypted.msg)
• send the message
• verify(by sender public key)
• decrypt(by recipient private key)

  ##### sender ####
  # encrupt
  gpg -ea -o secret.txt.asc -r "recipient" secret.txt
  # sign (optional)
  gpg -o encrupted.sig -sa secret.txt.asc
  
  ##### recipient #####
  gpg --verify encrupted.sig (if signed)
  # get the message (still encrupted) (if signed)
  gpg -o encrupted -d encrupted.sig
  # decrypt the message
  gpg -o decrypted -d encrupted
