The data to decrypt.
The initialization vector.
The padding mode used to produce the ciphertext and remove during decryption.
The feedback size, specified in bits.
When this method returns, contains the total number of bytes written to destination
.
true
if destination
was large enough to receive the decrypted data; otherwise, false
.
A derived class has not provided an implementation.
Derived classes must override this and provide an implementation.
