The cipher is initialized for one of the following four operations:
encryption, decryption, key wrapping or key unwrapping, depending on
the value of opmode
.
If this cipher requires an initialization vector (IV), it will get
it from random
.
This behaviour should only be used in encryption or key wrapping
mode, however.
When initializing a cipher that requires an IV for decryption or
key unwrapping, the IV
(same IV that was used for encryption or key wrapping) must be provided
explicitly as a
parameter, in order to get the correct result.
This method also cleans existing buffer and other related state information.
