NAME¶
asn1_der_decoding2 - API function
SYNOPSIS¶
#include <libtasn1.h>
int asn1_der_decoding2(asn1_node * element, const void *
ider, int * max_ider_len, unsigned int
flags, char * errorDescription);
ARGUMENTS¶
- asn1_node * element
- pointer to an ASN1 structure.
- const void * ider
- vector that contains the DER encoding.
- int * max_ider_len
- pointer to an integer giving the information about the
maximal number of bytes occupied by * ider . The real size of the
DER encoding is returned through this pointer.
- unsigned int flags
- flags controlling the behaviour of the function.
- char * errorDescription
- null-terminated string contains details when an error
occurred.
DESCRIPTION¶
Fill the structure *
element with values of a DER encoding string. The
structure must just be created with function
asn1_create_element().
If
ASN1_DECODE_FLAG_ALLOW_PADDING flag is set then the function will
ignore padding after the decoded DER data. Upon a successful return the value
of *
max_ider_len will be set to the number of bytes decoded.
RETURNS¶
ASN1_SUCCESS if DER encoding OK,
ASN1_ELEMENT_NOT_FOUND if
ELEMENT is
NULL, and
ASN1_TAG_ERROR or
ASN1_DER_ERROR if the der encoding doesn't match the structure name (*
ELEMENT deleted).
