Answer 1

For the benefit of anyone out there trying to use multi-line variable (i.e RSA private keys) in a dotenv file (should work for any configuration file though).

1) make each line of the private key end with a \n

  such that first line**\n**
  second line**\n**
  and the  third line and so on

2) now make the variable in single line in double quotes as follow KEY="such that first line**\nsecond line\nand the third line and so on\n**"

3) Ensure you add a leading and trailing \n character for the key as well KEY="\nsuch that first line**\nsecond line\nand the third line and so on\n**"

4) now in your code (i.e node, of course if you do not have access to code you have rely on the behaviour of the platform/app)

goodlyRepresentedKey = (process.env.KEY).replace(/\n/g, '\n');

(if biggly why not goodly)
