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...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
