Thank you. As I can understand stare vs peek on step1 differentiated by default action (bump/splice) applied later when this action is not explicitly defined.

I'm confusing because code contain many things in terms clientFirst, serverFirst (for example const bool clientFirstBump = ) but in configuration its deprecated and no clue how it relate to peek/stare. Also there is a flag sslPeek but no flag sslStare. While sslPeek seems not related to peek/stare and mean "internal ssl-bump request to get server cert".

In conclusion my thought is that peek/stare on step1 are the same when every sslbump step is explicitly defined in configuration.
