    Methods in javax.crypto that throw ExemptionMechanismException
    Modifier and Type | Method | Description
    --- | --- | ---
    `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.
