Passing Cert chain file as RAW buffer

[Brahmaji K <brahmaji.k@xxxxxxxxx>]

Hi Team,

I have cert chain file as shown below:

----- BEGIN the CERTIFICATE -----
:
:
----- the END the CERTIFICATE -----
----- BEGIN the CERTIFICATE -----
:
:
----- the END the CERTIFICATE -----
----- BEGIN the CERTIFICATE -----
:
:
----- the END the CERTIFICATE -----

Is it possible to convert this cert chain file to raw buffer (i.e., unsigned char *buf)? If possible, how can this buffer be validated?

Thank you very much for your help.
