### Uses of ExemptionMechanismException in javax.crypto

Methods in javax.crypto that throw ExemptionMechanismException
`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 the `output` buffer, starting at `outputOffset` inclusive.
`protected abstract void` ExemptionMechanismSpi.`engineInit​(Key key)` Initializes this exemption mechanism with a key.
`protected abstract void` ExemptionMechanismSpi.`engineInit​(Key key, AlgorithmParameters params)` Initializes this exemption mechanism with a key and a set of algorithm parameters.
`protected abstract void` ExemptionMechanismSpi.`engineInit​(Key key, AlgorithmParameterSpec params)` Initializes this exemption mechanism with a key and a set of algorithm parameters.
`byte[]` ExemptionMechanism.`genExemptionBlob()` Generates the exemption mechanism key blob.
`int` ExemptionMechanism.`genExemptionBlob​(byte[] output)` Generates the exemption mechanism key blob, and stores the result in the `output` buffer.
`int` ExemptionMechanism.`genExemptionBlob​(byte[] output, int outputOffset)` Generates the exemption mechanism key blob, and stores the result in the `output` buffer, starting at `outputOffset` inclusive.
`void` ExemptionMechanism.`init​(Key key)` Initializes this exemption mechanism with a key.
`void` ExemptionMechanism.`init​(Key key, AlgorithmParameters params)` Initializes this exemption mechanism with a key and a set of algorithm parameters.
`void` ExemptionMechanism.`init​(Key key, AlgorithmParameterSpec params)` Initializes this exemption mechanism with a key and a set of algorithm parameters.
`boolean` ExemptionMechanism.`isCryptoAllowed​(Key key)` Returns whether the result blob has been generated successfully by this exemption mechanism.
