| Methods Summary |
|---|
| public static int | addProvider(java.security.Provider provider)Adds the given {@code provider} to the collection of providers at the
next available position.
If a {@code SecurityManager} is installed, code calling this method needs
the {@code SecurityPermission} {@code insertProvider.NAME} (where NAME is
the provider name) to be granted, otherwise a {@code SecurityException}
will be thrown.
return insertProviderAt(provider, 0);
|
| public static java.lang.String | getAlgorithmProperty(java.lang.String algName, java.lang.String propName)Returns value for the specified algorithm with the specified name.
if (algName == null || propName == null) {
return null;
}
// BEGIN android-changed
String prop = "Alg." + propName + "." + algName; //$NON-NLS-1$
// END android-changed

|
| public static java.util.Set | getAlgorithms(java.lang.String serviceName)Returns a {@code Set} of all registered algorithms for the specified
cryptographic service. {@code "Signature"}, {@code "Cipher"} and {@code

|
| public static java.lang.String | getProperty(java.lang.String key)Returns the value of the security property named by the argument.
If a {@code SecurityManager} is installed, code calling this method needs
the {@code SecurityPermission} {@code getProperty.KEY} (where KEY is the
specified {@code key}) to be granted, otherwise a {@code
SecurityException} will be thrown.

installed.

|
| public static synchronized java.security.Provider[] | getProviders(java.util.Map filter)Returns the array of providers which meet the user supplied set of
filters. The filter must be supplied in one of two formats:

be an empty string. CRYPTO_SERVICE_NAME.ALGORITHM_OR_TYPE

the value of the filter map entry.

| public static synchronized int | insertProviderAt(java.security.Provider provider, int position)Insert the given {@code Provider} at the specified {@code position}. The
positions define the preference order in which providers are searched for
requested algorithms.
If a {@code SecurityManager} is installed, code calling this method needs
the {@code SecurityPermission} {@code insertProvider.NAME} (where NAME is
the provider name) to be granted, otherwise a {@code SecurityException}
will be thrown.

// installed, else return -1; if (position <1) or (position > max

| public static synchronized void | removeProvider(java.lang.String name)Removes the {@code Provider} with the specified name form the collection
of providers. If the the {@code Provider} with the specified name is
removed, all provider at a greater position are shifted down one
position.
Returns silently if {@code name} is {@code null} or no provider with the
specified name is installed.
If a {@code SecurityManager} is installed, code calling this method needs
the {@code SecurityPermission} {@code removeProvider.NAME} (where NAME is
the provider name) to be granted, otherwise a {@code SecurityException}
will be thrown.
