Hello, I'm ST47. I wanted to let you know that I reverted one of your recent contributions —specifically this edit to Block cipher mode of operation— because it did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Help desk. Thanks. ST47 (talk) 04:44, 4 May 2019 (UTC)

Please refrain from making test edits in Wikipedia pages, such as those you made to Block cipher mode of operation, even if you intend to fix them later. Your edits have been reverted.

Please stop making test edits to Wikipedia, as you did to Self-concept. It is considered vandalism, which, under Wikipedia policy, can lead to being blocked from editing. If you would like to experiment again, please use the sandbox. Zefr (talk) 20:36, 24 June 2019 (UTC)
