3 How to work with X.509 certificates.

One of the most complex data formats are the X.509 certificates. KSBA provides an easy to use interface to handle them.

The ksba_cert_t type is a handle for an X.509 certificate.

— Data type: ksba_sexp_t

The ksba_sexp_t type describes a canonically encoded S-expression stored in a memory buffer. It is alias for unsigned char *. Note that a length argument is not required because the length of such an S-expression is intrinsically available.
