@kelalaka ah! no need now that I know where to look for it. Thanks.

can you add the key for the subscripts?

In Japanese, I use "me" and "the other party". 私と相手の人. Alice and Bob are fine in a western context. Chinese also has a similar structure. I won't get too woke up about it.

Bye. I appreciate all of the detailed insights into cryptography. I appreciate the time.

You can also put things in your native language as a comment. Although, we generally post in English, many of us speak other languages as well. Between the original post, and the notes, someone might be able to edit your post to make more sense.
