Name

asn1_der_decoding2 - API function

Synopsis

int  asn1_der_decoding2(asn1_node  *  element, const void * ider, int *
max_ider_len, unsigned int flags, char * errorDescription);

Description

asn1_der_decoding2(3)              libtasn1              asn1_der_decoding2(3)



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 max-
                   imal  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.

       If ASN1_DECODE_FLAG_STRICT_DER flag is set then the function  will  not
       decode any BER-encoded elements.

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).
