Must be 16 bytes" (InvalidParameterValue). In this example, when we initialized the vector v1, it contained 2 elements.Thus its length was 2 with v1[0] = 5 and v1[1] = 6. v1.resize(5) resized the vector so that it contains 5 elements. For CFB mode, the IV must never be reused for different messages under the same key; for CBC mode, the IV must never be reused for different messages under the same key, and must be unpredictable in advance by an attacker.
