For more complex encoding than octet strings libtasn1 is the easiest to
use (although the complexity of PostalString is really borderline and
making a custom parser may be actually faster).
I was thinking about gnutls_x509_crt_get_dn() (under the hood is
gnutls_x509_crt_get_dn()) that decodes DNs to plain LDAP strings.
