as3crypto PEM.readRSAPublicKey returns null
- by www.jefferyfernandez.id.au
I am trying to implement a bit of encryption in my Air application while communication with a PHP backend server. For this purpose I am using as3crypto library and I can't read the public key to make the encryption possible. Here is my action script code:
var rsa:RSAKey = PEM.readRSAPublicKey(this.readApplicationFileContents('server.crt'));
if ( rsa )
{
var encodeSource:ByteArray = Hex.toArray(Hex.fromString("Hello World"));
var encodeDestination:ByteArray = new ByteArray;
var encodeDestination2:ByteArray = new ByteArray;
rsa.encrypt(encodeSource, encodeDestination, encodeSource.length)
rsa.decrypt(encodeDestination, encodeDestination2, encodeDestination.length);
trace(encodeDestination2.toString());
}
private function readApplicationFileContents(filePath:String):String
{
var fileObject:File = File.applicationDirectory.resolvePath(filePath);
var fileStream:FileStream = new FileStream();
fileStream.open(fileObject, FileMode.READ);
var fileContents:String = fileStream.readUTFBytes(fileStream.bytesAvailable);
return(fileContents);
}
readApplicationFileContents function returns the proper certificate contents as a string. But rsa variable always returns null.
It would have been easier if I was able to compile the as3crypto library so I can debug through the source, but I can't get the library to compile and can't find any instructions to do the same. Anyone have a clue what's wrong?
PS. Sorry first time poster and I can't seem to get the syntax highlighting right. Must be Chrome is not working well with the editor.
