IllegalArgumentException

[EdmondChuiHW]

Not sure if it is Android specific, but testing on both 2.3.6 and 4.1.1 devices causes this Exception.

E/AndroidRuntime(10087): java.lang.IllegalArgumentException: Bad limit (capacity 57): 73

Do you have a test case?

[EdmondChuiHW]

I found out the reason while I'm testing. When the input is an empty String, the second entry after it will cause this error.

Here is a test case, after encrypting the first empty String, encrypting "Jacob" does not have any problem, however encrypting "Sophia" will cause such Exception to be thrown. And the solution is to do an empty String test.

I believe an empty String is not a valid input for the Crypter then.

Thanks!
