Keygenerator.getinstancedes

Therefore, it is recommended to explicitly initialize the KeyGenerator instead of relying on provider-specific defaults. Consult the release documentation for your implementation to see if any other algorithms are supported. This is the same name that was specified in one of the getInstance calls that created this KeyGenerator object. This method traverses the list of registered security Providers, starting with the most preferred Provider.

A new KeyGenerator object encapsulating the KeyGeneratorSpi implementation from the first Provider that supports the specified algorithm is returned. Note that the list of registered providers may be retrieved via the Security. A new KeyGenerator object encapsulating the KeyGeneratorSpi implementation from the specified provider is returned.

The specified provider must be registered in the security provider list. A new KeyGenerator object encapsulating the KeyGeneratorSpi implementation from the specified Provider object is returned. String getAlgorithm Returns the algorithm name of this KeyGenerator object.

Provider getProvider Returns the provider of this KeyGenerator object. Methods inherited from class java. Parameters: keyGenSpi - the delegate provider - the provider algorithm - the algorithm Method Detail getAlgorithm public final String getAlgorithm Returns the algorithm name of this KeyGenerator object. This is the same name that was specified in one of the getInstance calls that created this KeyGenerator object.

Returns: the algorithm name of this KeyGenerator object. This method traverses the list of registered security Providers, starting with the most preferred Provider. A new KeyGenerator object encapsulating the KeyGeneratorSpi implementation from the first Provider that supports the specified algorithm is returned. Note that the list of registered providers may be retrieved via the Security. Parameters: algorithm - the standard name of the requested key algorithm.

Returns: the new KeyGenerator object. Throws: NullPointerException - if the specified algorithm is null. A new KeyGenerator object encapsulating the KeyGeneratorSpi implementation from the specified provider is returned. So, how do I extract the key contained in a text file? And pass as an input to this statement? Or else is it possible to take the key as an input from the user during both the encryption and decryption process? But please remember that DES is unsecure today it can be relatively easily bruteforced.
