Never mind, I have come up with a solution:
package com.yourpackage.signature;
import java.io.IOException;
import java.security.InvalidKeyException;
import java.security.NoSuchAlgorithmException;
import java.util.Date;
import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
import org.apache.geronimo.mail.util.Base64; //can be whichever flavor of encoder you'd like
public class SignatureGenerator {
public static final String ACCESS_ID = "member-XXXXXXX";
public static final String SECRET_KEY = "XXXXXXXXXXXXXXXXXXXXXXXXXXx";
//expireTime should be in seconds since Jan 1 1970 : new Date().getTime()/1000) + X
public static String generateSignature(String data, String key, String expireTime, String algorithm)
throws InvalidKeyException, NoSuchAlgorithmException, IOException {
data += expireTime;
byte[] hmacData = null;
SecretKeySpec secretKey = new SecretKeySpec(key.getBytes("UTF-8"),
algorithm);
Mac mac = Mac.getInstance(algorithm);
mac.init(secretKey);
hmacData = mac.doFinal(data.getBytes("UTF-8"));
String encoded = new String(Base64.encode(hmacData));
return encoded;
}
public static void main(String[] args) {
try {
Long longTime = new Long(new Date().getTime()/1000) + 60;
System.out.println(longTime);
String data = ACCESS_ID + "\n";
System.out.println(generateSignature(data, SECRET_KEY, String.valueOf(longTime), "HMACSHA1"));
} catch (Exception e) {
e.printStackTrace();
}
}
}
