Thank you very much!!! It worked but i dont like it :P (i know it can be done with python) but isnt there any way to do it with pen and paper? using that site i feel like cheating...

ok then is there any specific method to follow other than XORing? How would you normally decrypt/encrypt with CBC method given a K and a IV?(just give me a link/source if you will/have so i dont waste your time on newbie questions :D)

ok i get what ou are syaing but just to make it more clear, i am following a cryptography course in coursera.org where given the k and the IV i have to decrypt a CT, so i am doing the flowing: (IV xor c_1) xor k (for the first block) and (m_1 xor c_2) xor k (for the second one and so on) but that does not return any reasonable result what am i doin wrong?

yes but lets say that the key is 10101010 and the IV 01010101 how do i encrypt the 11110000 i need to know the procedure AFTER the XOR operation.
