If format is null, the
primary encoding format for parameters is used. The primary encoding
format is ASN.1, if an ASN.1 specification for these parameters
exists.
Returns: the parameters encoded using the specified encoding scheme.
Parameters:
- format - the name of the encoding format.
Throws:
- IOException - on encoding errors, or if this parameter object has not been initialized.

  Returns a parameter object for the specified algorithm.

  Returns a parameter object for the specified algorithm.

This method traverses the list of registered security Providers, starting with the most preferred Provider. A new AlgorithmParameters object encapsulating the AlgorithmParametersSpi 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.getProviders() method.

The returned parameter object must be initialized via a call to init, using an appropriate parameter specification or parameter encoding.
Returns: the new parameter object.
Parameters:
- algorithm - the name of the algorithm requested. See Appendix A in the Java Cryptography Architecture API Specification & Reference for information about standard algorithm names.
Throws:
- NoSuchAlgorithmException - if no Provider supports an AlgorithmParametersSpi implementation for the specified algorithm.

  Returns a parameter object for the specified algorithm.

  Returns a parameter object for the specified algorithm.

A new AlgorithmParameters object encapsulating the AlgorithmParametersSpi implementation from the specified Provider object is returned. Note that the specified Provider object does not have to be registered in the provider list.

The returned parameter object must be initialized via a call to init, using an appropriate parameter specification or parameter encoding.
Returns: the new parameter object.
Parameters:
- algorithm - the name of the algorithm requested. See Appendix A in the Java Cryptography Architecture API Specification & Reference for information about standard algorithm names.
- provider - the name of the provider.
Throws:
- NoSuchAlgorithmException - if an AlgorithmParameterGeneratorSpi implementation for the specified algorithm is not available from the specified Provider object.
- IllegalArgumentException - if the provider is null.
