Wrong key size

[IgorGanapolsky]

Hello,
I am unable to use your library to decrypt strings. I get an error:

Wrong key size
at javax.crypto.spec.DESKeySpec.(DESKeySpec.java:155)
at com.mobapphome.mahencryptorlib.MAHEncryptor.(MAHEncryptor.java:29)
at com.mobapphome.mahencryptorlib.MAHEncryptor.newInstance(MAHEncryptor.java:46)

Me either, how can resolve the "Wrong key size"?
