LOL, good lord, no. I published a book about SSL around 10 years ago or so (one of only, I believe, five or six such books). I found myself unexpectedly back on the job market around 2017 and I applied for job listings specifically related to SSL. Never heard back from a single one of them. The only time the book came up was when I interviewed for the (completely non-SSL, non-security-focused) job I have now when one of the interviewers said, "You published a book about SSL? But you can do other stuff, right?"
