asn1_expand_octet_string(3) API function


#include <libtasn1.h>

asn1_retCode asn1_expand_octet_string(ASN1_TYPE definitions, ASN1_TYPE * element, const char * octetName, const char * objectName);


ASN1_TYPE definitions
ASN1 definitions
ASN1_TYPE * element
pointer to an ASN1 structure
const char * octetName
name of the OCTECT STRING field to expand.
const char * objectName
name of the OBJECT IDENTIFIER field to use to define the type for expansion.


Expands an "OCTET STRING" element of a structure created from a DER decoding process (the asn1_der_decoding() function). The type used for expansion is the first one following the definition of the actual value of the OBJECT IDENTIFIER indicated by OBJECTNAME.


ASN1_SUCCESS if substitution OK, ASN1_ELEMENT_NOT_FOUND if objectName or octetName are not correct, ASN1_VALUE_NOT_VALID if it wasn't possible to find the type to use for expansion, or other errors depending on DER decoding.
