| protected abstract byte[] | ExemptionMechanismSpi. engineGenExemptionBlob()Generates the exemption mechanism key blob. | 
| protected abstract int | ExemptionMechanismSpi. engineGenExemptionBlob(byte[] output,
                      int outputOffset)Generates the exemption mechanism key blob, and stores the result in
