Guess what? It's the same as a provisional cast on except for the last loop you crochet. I was dubious about finding anything and was thinking it would have to be pretty much the same thing. I'm glad you asked!
And here's a video for the crochet bind off which also gives you a neat chain edge. If you knit tightly, you might use a size larger crochet hook or knitting needle for both the cast on and bind off to make sure they are loose and stretchy.
It's kind of funny actually but casting off and binding off are almost actually the same thing except for the last stitch. This confused me a little bit when i first started following patterns and then I realised that i didn't have to learn anything new, just keep doing what I was originally doing.
