pointer to an ASN1 structure

 

elementName

name of the element to fill

 

ider

vector that contains the DER encoding of the whole structure.

 

len

number of bytes of *der: der[0]..der[len-1]

 

errorDescription

null-terminated string contains details when an error occurred.

 

Returns

                            int *end);

Find the start and end point of an element in a DER encoding string. I mean that if you have a der encoding and you have already used the function asn1_der_decoding() to fill a structure, it may happen that you want to find the piece of string concerning an element of the structure.

One example is the sequence "tbsCertificate" inside an X509 certificate.

Note that since libtasn1 3.7 the ider and ider_len parameters can be omitted, if the element is already decoded using asn1_der_decoding().

Parameters

element

pointer to an ASN1 element

 

ider

vector that contains the DER encoding.

asn1_expand_any_defined_by ()

int
asn1_expand_any_defined_by (asn1_node_const definitions,

Parameters

definitions

ASN1 definitions

 

element

pointer to an ASN1 structure

 

Returns

ASN1_SUCCESS if Substitution OK, ASN1_ERROR_TYPE_ANY if some "ANY DEFINED BY" element couldn't be expanded due to a problem in OBJECT_ID -> TYPE association, or other error codes depending on DER decoding.

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.

Parameters

ASN1 definitions

 

element

pointer to an ASN1 structure

 

octetName

name of the OCTECT STRING field to expand.

See ASN1_VERSION for a suitable req_version string.

Parameters

Returns

Version string of run-time library, or NULL if the run-time library does not meet the required version number.


asn1_perror ()
