4Subject: [PATCH] Throw exception when IV is used with ECB or CTR
5
6The IV parameter is currently ignored when initializing
7a cipher in ECB or CTR mode.
8
9For CTR mode, it is confusing: it takes some time to see
10that a different parameter is needed (the counter).
11
12For ECB mode, it is outright dangerous.
13
14This patch forces an exception to be raised.

16Upstream-Status: Backport
