Passing Cert chain file as RAW buffer

[Brahmaji K]

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.
