### Uses of ExemptionMechanismException in javax.crypto

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