SYNOPSIS

       #include <shishi.h>

       int  shishi_asn1_to_der_field(Shishi  * handle, Shishi_asn1 node, const char * field, char
       ** der, size_t * len);

ARGUMENTS

       Shishi * handle
                   shishi handle as allocated by shishi_init().

       Shishi_asn1 node

       const char * field
                   name of field in node to extract.

       char ** der output array that holds DER encoding of field in node.

       size_t * len
                   output variable with length of der output array.

DESCRIPTION

       Extract newly allocated DER representation of specified ASN.1 field.

RETURN VALUE

       Returns SHISHI_OK if successful,  or  SHISHI_ASN1_ERROR  if  DER  encoding  fails  (common
