You have most likely made an error in your code somewhere.  
When asking this type of question you really need to post snippets from you code. List all the configuration steps, the encoding, encryption, math and decryption steps. I can’t even tell what scheme you are trying to use.

If you want to debug yourself. try decrypting A, B and C first, and make sure you encoded and encrypted the way you think.
