javascript - How can I convert RSA PlblicKey XML to PEM format -


i receive rsa key c# server through httprequest,

many encrypt lib need pem format.

find solution @ this

xml pem in node.js

can't use in javscript h5 project, have other solution?

your xml seems propietary format

<rsakeyvalue>      <modulus>1znidpbicmco7k/53tktsykqxlg5mcws8kvtijs4tyeu4w/fevwypotv+stnb4vt</modulus>     <exponent>aqab</exponent> </rsakeyvalue>

you need cryptographic library forge build rsa public key modulus , exponent. based on thread , can use code similar this

// parse xml var rsakeyvalue = ...  var biginteger = forge.jsbn.biginteger; function parsebiginteger(b64) {      return new biginteger(forge.util.createbuffer(forge.util.decode64(b64)).tohex(), 16);  }   //create forge public key modulus , exponent  var publickey = forge.pki.setrsapublickey(        parsebiginteger(rsakeyvalue.modulus), // n        parsebiginteger(rsakeyvalue.exponent)); // e   // convert forge public key pem-format  var pem = forge.pki.publickeytopem(publickey);

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
