Class BlobCrypterSecurityTokenCodec

java.lang.Object
  org.apache.shindig.auth.BlobCrypterSecurityTokenCodec

All Implemented Interfaces:

SecurityTokenCodec

public class BlobCrypterSecurityTokenCodec
extends Object
implements SecurityTokenCodec

Provides security token decoding services. Configuration is via containers.js. Each container should specify (or inherit) securityTokenKeyFile: path to file containing a key to use for verifying tokens. signedFetchDomain: oauth_consumer_key value to use for signed fetch using default key. Creating a key is best done with a command line like this:

     dd if=/dev/random bs=32 count=1  | openssl base64 > /tmp/key.txt
 

Wire format is "<container>:<encrypted-and-signed-token>"

Since:

2.0.0

Method Detail

loadCrypterFromFile

protected BlobCrypter loadCrypterFromFile(File file)
                                   throws IOException

Load a BlobCrypter from the specified file. Override this if you have your own BlobCrypter implementation.
