/**
* Returns an array containing all installed providers that satisfy the specified* selection
* criteria, or null if no such providers have been installed. The returned providers are ordered
* according to their <a href= "#insertProviderAt(java.security.Provider, int)">preference
* order</a>.
*
* <p>The selection criteria are represented by a map. Each map entry represents a selection
* criterion. A provider is selected iff it satisfies all selection criteria. The key for any
* entry in such a map must be in one of the following two formats:
*
* <ul>
* <li><i><crypto_service>.<algorithm_or_type></i>
* <p>The cryptographic service name must not contain any dots.
* <p>The value associated with the key must be an empty string.
* <p>A provider satisfies this selection criterion iff the provider implements the
* specified algorithm or type for the specified cryptographic service.
* <li><i><crypto_service>.<algorithm_or_type> <attribute_name></i>
* <p>The cryptographic service name must not contain any dots. There must be one or more
* space charaters between the <i><algorithm_or_type></i> and the
* <i><attribute_name></i>.
* <p>The value associated with the key must be a non-empty string. A provider satisfies
* this selection criterion iff the provider implements the specified algorithm or type for
* the specified cryptographic service and its implementation meets the constraint expressed
* by the specified attribute name/value pair.
* </ul>
*
* <p>See Appendix A in the <a href= "../../../guide/security/CryptoSpec.html#AppA"> Java
* Cryptogaphy Architecture API Specification & Reference </a> for information about standard
* cryptographic service names, standard algorithm names and standard attribute names.
*
* @param filter the criteria for selecting providers. The filter is case-insensitive.
* @return all the installed providers that satisfy the selection criteria, or null if no such
* providers have been installed.
* @throws InvalidParameterException if the filter is not in the required format
* @throws NullPointerException if filter is null
