constant doesn't allow any form of expression, you can't even do
constant mykey = "abc" & "def"

A "clean" solution ?
  - assign to a variable instead
  - custom prop
  - since you're generating it externally - put it in a fixed-name file, 
and have your script read that file in

btw if I take the above code, and convert from using a constant to a 
variable, I'd get
    put "-----BEGIN PUBLIC KEY-----" \
       & "ABC123"\
       & "DEF456"\
       & "-----END PUBLIC KEY-----" into myVar

but that means it's become a single line, instead of 4 lines.
Should it be
    put  "-----BEGIN PUBLIC KEY-----" &CR& \
       & "ABC123"  &CR& \
       & "DEF456" &CR& \
       & "-----END PUBLIC KEY-----" into myVar
??
