NAME

sc_app_info_t - OpenSC application structure

SYNOPSIS

#include <opensc.h>

#define SC_MAX_AID_SIZE            16

typedef struct sc_app_info {
     unsigned char aid[SC_MAX_AID_SIZE];
     size_t aid_len;
     char *label;
     sc_path_t path;
     unsigned char *ddo;
     size_t ddo_len;

     const char *desc;
     int rec_nr;
} sc_app_info_t;

DESCRIPTION

This structure describes a smart card application. It contains the
following members:

aid

The applications's AID. An AID uniquely identifies an application, and consists of an RID (a 5-byte "Registered Application Provider
Identifier") and a PIX, which identifies an application by that
provider. For example, the RID for PKCS#15 consists of the bytes A0 00 00 00 63, and the PIX is the string "PKCS-15". Thus, the AID of a PKCS#15 application on a smart card is A0 00 00 00 63 50 4B 43 53 2D 31.

aid_len

The length of the AID in bytes.

label

A UTF-8 string describing the application.

path

The application's full path on the card, starting at the MF.

ddo

ddo_len

desc

A description of the application, if available.

rec_nr

If the EF(DIR) file is record-structured, this has the record
number in which this application is stored. Otherwise, this is -1.
