If secret.getBytes() fails, then y2 will be undefined and y1.modPow(y2, P); will throw an exception [1] If MessageDisgest.getInstance() or id.getBytes() fail then an exception will be thrown at sha.digsst() or BigIntegerHelper.ByteArrayToBigIntegerWithoutSign [2][3] The code should abort / return error in these cases. [1] - https://github.com/mozilla-services/android-sync/blob/master/src/main/java/org/mozilla/gecko/sync/jpake/JPakeCrypto.java#L153 [2] - https://github.com/mozilla-services/android-sync/blob/master/src/main/java/org/mozilla/gecko/sync/jpake/JPakeCrypto.java#L297 [3] - https://github.com/mozilla-services/android-sync/blob/master/src/main/java/org/mozilla/gecko/sync/jpake/BigIntegerHelper.java#L45
The parameter should not be a string, but a byte array. Whatever conversion from string to byte array that might be necessary should happen in the non-crypto code.
