I'm trying to make a txt file with a generated key into 1 line. example:

<----- key start ----->
lkdjasdjskdjaskdjasdkj
skdhfjlkdfjlkdsfjsdlfk
kldshfjlsdhjfksdhfksdj
jdhsfkjsdhfksdjfhskdfh
jhdfkjsdhfkjsdhfkjsdhf
<----- key stop ----->

I want it to look like:

lkdjasdjskdjaskdjasdkjskdhfjlkdfjlkdsfjsdlfkkldshfjlsdhjfksdhfksdjjdhsfkjsdhfksdjfhskdfhjhdfkjsdhfkjsdhfkjsdhf

Notice I also want the lines <----- key start -----> and <----- key stop -----> removed. How can I do this? Would this be done with sed?
