java - ¿Cómo integrar Aadhaar Card Authentication Api para la verificación del número de Aadhaar en PHP?

curl

Question

Quiero integrar la API de Autenticación de tarjetas Aadhaar para la verificación del número de Aadhaar en PHP. Intenté this y escribí el código para el acceso a la API.

¿Cómo puedo generar los datos del campo de encriptación XML a continuación en PHP? Este código de muestra está escrito en Java.

<Auth uid="" tid="" ac="" sa="" ver="" txn="" lk="">
<Uses pi="" pa="" pfa="" bio="" bt="" pin="" otp=""/>
<Tkn type="" value=""/>
<Meta udc="" fdc="" idc="" pip="" lot=”G|P” lov=""/>
<Skey ci="" ki="">encrypted and encoded session key</Skey>
<Data type=”X|P”>encrypted PID block</Data>
<Hmac>SHA-256 Hash of Pid block, encrypted and then encoded</Hmac>
<Signature>Digital signature of AUA</Signature>
</Auth>

Answer 1

Para generar el XML, puede usar esta biblioteca para generarlo con bastante facilidad:

Para el cifrado; Podría estar equivocado, pero parece que ( this ) puede generar los resultados codificados en Java una vez y simplemente pegar los resultados en sus variables de PHP.
