The IV/counter affect the cipher input and so the keystream varies. The reason this can be decrypted is that the decrypter knows both the key and the IV/counter. They can calculate exactly the same function as the encrypter did, resulting in the same keystream block, which a XOR then cancels out. data sharing in redshift
