Hello, I'm John of Reading. An edit that you recently made to Diffie–Hellman key exchange seemed to be a test and has been reverted. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! John of Reading (talk) 17:54, 30 December 2021 (UTC)

Please refrain from making unconstructive edits to Wikipedia, as you did at Ethiopian historiography. Your edits appear to constitute vandalism and have been reverted. If you would like to experiment, please use the sandbox. Repeated vandalism may result in the loss of editing privileges. Thank you. Leoprix (talk) 18:21, 31 December 2021 (UTC)
