I am working on SSL VPN BP.

CA certificate is one of the resources. We decided to use PEM formatted certificates. It is multi-line string 

  1 -----BEGIN CERTIFICATE-----
  2 MIID3TCCA0agAwIBAgIJAKRWnul3NJnrMA0GCSqGSIb3DQEBBQUAMIGmMQswCQYD
 <snip>
 21 0vO728pEcn6QtOpU7ZjEv8JLKRHwyq8kwd8gKMflWZRng4R2dj3cdd24oYJxn5HW
 22 atXnq+N9H9dFgMfw5NNefwJrZ3zAE6mu0bAIoXVsKT2S
 23 -----END CERTIFICATE-----

Is there a standard way to represent this as single line string? Maybe there is some other project that passes certificates on command line/url. 

I am looking for some accepted way to represent PEM formatted file on command line. 

I am thinking of concatenating all lines into single string and rebuilding the file when configuration file is generated.Will we hit any CLI size limitations if we pass long strings.

Thanks,
