2. Integration API function

 

1) verifyKEYL function(When using login-ID)

 

- NAME

  verifyKEYL

 

- SYNOPSIS

  int verifyKEYL(const char *login_id, const char *phone_no, const char *cycle_time, const char *corr_time, const char *key_method, char *auth_key)

 

- DESCRIPTION

A function that verifies whether the entered one-time authentication key is correct.

 

login_id: Set the ID entered in the login-ID field of the login screen.

phone_no: Login-ID set user's smart phone number only with numbers.

cycle_time: Set the generation cycle (3~60 seconds) of one-time authentication key specified for each user.

corr_time: This is the guarantee error time (seconds) of the one-time authentication key.

              Set only for authentication cards. (0 seconds)

key_method: Set the one-time authentication key verification method (app1, app256, app384,

app512: app, card1, card256, card384, card512: authentication card).

auth_key: Set the one-time authentication key created and entered in the BaroPAM app on the login screen.

 

If the generation period of the smart phone number for each user and the one-time authentication key designated for each individual is different from the generator of the one-time authentication key, verification may fail because the one-time authentication key is different. You must match the information.

 

- RETURN VALUES

 On success, 1 is returned, and on failure, 0 is returned.

 

 

2) verifyKEYP function(When using secure key)

 

- NAME

  verifyKEYP

 

- SYNOPSIS

  int verifyKEYP(const char *secure_key, const char *cycle_time, const char *corr_time, const char *key_method, char *auth_key)

 

- DESCRIPTION

A function that verifies whether the entered one-time authentication key is correct.

 

Secure_key: Set the secure key given for each user or OTP card.

cycle_time: Set the generation cycle (3~60 seconds) of one-time authentication key specified for each user.

corr_time: This is the guarantee error time (seconds) of the one-time authentication key.

              Set only for authentication cards. (900 seconds)

key_method: Set the one-time authentication key verification method (app1, app256, app384,

app512: app, card1, card256, card384, card512: authentication card).

auth_key: Set the one-time authentication key created and entered in the BaroPAM app on the login screen.

 

If the generation cycle of the secure key and one-time authentication key specified for each user or card is different from the one-time authentication key generator, verification may fail because the one-time authentication key is different. You must match the information.

 

- RETURN VALUES

 On success, 1 is returned, and on failure, 0 is returned.

 

 

3. Authentication key verification part

 

1) Example of using authentication key verification module

 

Sample program) verifyKEYL function (when using login-ID)

 

#include <errno.h>

#include <stdarg.h>

#include <stdio.h>

#include <stdlib.h>

#include <string.h>

 

#include "BaroKEYx.h"

 

int main(int argc, char *argv[]) {

    const char *login_id   = argv[1];    // Login-ID

    const char *phone_no   = argv[2];    // Phone number

    const char *cycle_time = argv[3];    // Cycle time

    const char *corr_time  = argv[4];    // Correction time

    const char *key_method = argv[5];    // Key method

          char *auth_key   = argv[6];    // Auth key

 

    // Authentication key verification

    int  bauth_key = verifyKEYL(login_id, phone_no, cycle_time, corr_time, key_method, auth_key);

 

    // Authentication key verification (success)

    if (bauth_key == 1) {

        printf("Auth key success.\n");

    // Authentication key verification (failure)

    } else {

        printf("Auth key faild.\n");

    }

}

 

Sample program) verifyKEYP function (when using secure key)

 

#include <errno.h>

#include <stdarg.h>

#include <stdio.h>

#include <stdlib.h>

#include <string.h>

 

#include "BaroKEYx.h"

 

int main(int argc, char *argv[]) {

    const char *secure_key = argv[1];    // Secure key

    const char *cycle_time = argv[2];    // Cycle time

    const char *corr_time  = argv[3];    // Correction time

    const char *key_method = argv[4];    // Key method

          char *auth_key   = argv[5];    // Auth key

 

    // Authentication key verification

    int  bauth_key = verifyKEYP(secure_key, cycle_time, corr_time, key_method, auth_key);

 

    // Authentication key verification (success)

    if (bauth_key == 1) {

        printf("Auth key success.\n");

    // Authentication key verification (failure)

    } else {

        printf("Auth key faild.\n");

    }

}
