Web9 de set. de 2016 · The short explanation is: IVs should be random and generated by a CSPRNG. IVs should not be reused. That is, don't encrypt plaintext "A" and plaintext "B" with the same IV. Every record should have its own IV. The IV is not a secret like the key. It can be stored in plaintext along with the cipher text.
