public final boolean equals(Object o) Implements abstract java.lang.Record.equals. Doc from java.lang.Record.equals. Indicates whether some other object is "equal to" this one. In addition to the general contract of `Object.equals`, record classes must further obey the invariant that when a record instance is "copied" by passing the result of the record component accessor methods to the canonical constructor, as follows: R copy = new R(r.c1(), r.c2(), ..., r.cn()); then it must be the case that `r.equals(copy)`.

In accordance with the general contract of `Object#toString()`, the `toString` method returns a string that "textually represents" this record. The result should be a concise but informative representation that is easy for a person to read. In addition to this general contract, record classes must further participate in the invariant that any two records which are equal must produce equal strings. This invariant is necessarily relaxed in the rare case where corresponding equal component values might fail to produce equal strings for themselves.

engineGetKeySize back to summary

protected int engineGetKeySize(Key key) throws InvalidKeyException

Overrides com.sun.crypto.provider.ARCFOURCipher.engineGetKeySize.

Doc from javax.crypto.CipherSpi.engineGetKeySize.

Returns the key size of the given key object in bits.

This concrete method has been added to this previously-defined abstract class. It throws an UnsupportedOperationException if it is not overridden by the provider.

InvalidKeyException:: if key is invalid

engineGetParameters back to summary

protected AlgorithmParameters engineGetParameters()

Overrides com.sun.crypto.provider.ARCFOURCipher.engineGetParameters.

Doc from javax.crypto.CipherSpi.engineGetParameters.

Returns the parameters used with this cipher.

The returned parameters may be the same that were used to initialize this cipher, or may contain additional default or random parameter values used by the underlying cipher implementation. If the required parameters were not supplied and can be generated by the cipher, the generated parameters are returned. Otherwise, null is returned.

engineInit back to summary

protected void engineInit(int opmode, Key key, AlgorithmParameterSpec params, SecureRandom random) throws InvalidKeyException, InvalidAlgorithmParameterException

Overrides com.sun.crypto.provider.ARCFOURCipher.engineInit.

Doc from javax.crypto.CipherSpi.engineInit.

Initializes this CipherSpi object with a key, a set of algorithm parameters, and a source of randomness.

The CipherSpi object is initialized for one of the following four operations: encryption, decryption, key wrapping or key unwrapping, depending on the value of opmode.

If this cipher requires any algorithm parameters and params is null, the underlying cipher implementation is supposed to generate the required parameters itself (using provider-specific default or random values) if it is being initialized for encryption or key wrapping, and raise an InvalidAlgorithmParameterException if it is being initialized for decryption or key unwrapping. The generated parameters can be retrieved using engineGetParameters or engineGetIV (if the parameter is an IV).

If this cipher requires algorithm parameters that cannot be derived from the input parameters, and there are no reasonable provider-specific default values, initialization will necessarily fail.

If this cipher (including its feedback or padding scheme) requires any random bytes (e.g., for parameter generation), it will get them from random.

Note that when a CipherSpi object is initialized, it loses all previously-acquired state. In other words, initializing a CipherSpi object is equivalent to creating a new instance of that CipherSpi object and initializing it.
