Im trying to create consumer secret / key pairs in my scala play application but i cant seem to get it to work correctly. I have the following code
import org.apache.commons.codec.binary.Base64
import javax.crypto.{KeyGenerator, Mac, SecretKey}
import javax.crypto.spec.SecretKeySpec
def hmacSha1(baseString:String) : String = {
val MAC_NAME = "HmacSHA1"
val keygen = KeyGenerator.getInstance(MAC_NAME);
val macKey = keygen.generateKey();
val mac = Mac.getInstance(MAC_NAME);
val secret = new SecretKeySpec(macKey.getEncoded(), mac.getAlgorithm());
mac.init(secret);
val digest = mac.doFinal(s.getBytes());
val result= new binary.Base64().encode(digest)
result.toString
}
but when i add in the baseString for something like "Anthony" I always get back a string that looks something like this
"[B@2008bf02"
where as i was hoping to get something that looks more like this
“w/FdJ7y1qwe3HX/VmPiACTn01Zc=“
You are not converting the encoded byte array to a string correctly. The Base64 class has a method to help you. Just do this:
mac.init(secret);
val digest = mac.doFinal(s.getBytes());
new binary.Base64().encodeBase64String(digest);
}
The more traditional way would be:
mac.init(secret);
val digest = mac.doFinal(s.getBytes());
val result= new binary.Base64().encode(digest)
new String(result, "ASCII");
}
