I am implementing the slideshare Connector using slideshare API.
I have to set this to the SHA1 hash of the concatenation of the shared
secret and the timestamp (ts). i.e. SHA1 (sharedsecret + timestamp).
package org.wso2.carbon.connector;
import java.math.BigInteger;
import java.security.MessageDigest;
import java.util.*;
import org.apache.synapse.MessageContext;
import java.io.UnsupportedEncodingException;
import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;
import org.apache.synapse.SynapseException;
import org.apache.synapse.mediators.AbstractMediator;
/**
* Created by vanii on 12/9/14.
*/
public class Encoder extends AbstractMediator {
public static final String sha1Key = "uri.var.sha1Key";
public void generateHash(MessageContext msgctx) throws
UnsupportedEncodingException,NoSuchAlgorithmException, InvalidKeyException {
StringBuilder baseString = new StringBuilder();
MessageDigest md = MessageDigest.getInstance("MD5");
String timeStamp=String.valueOf(System.currentTimeMillis() / 1000);
msgctx.setProperty("uri.var.ts",timeStamp);
String input = msgctx.getProperty("uri.var.sha1Key").toString() +
timeStamp;
md.update(input.getBytes());
String hash = String.format("%032x", new BigInteger(1,
md.digest()));
msgctx.setProperty("uri.var.hash",hash);
}
public boolean mediate(MessageContext msgctx) {
try {
generateHash(msgctx);
} catch (Exception e) {
throw new SynapseException(e);
}
return true;
}
}
I am getting but the response says hashing is not correct.
