  getAlgorithms

  public static Set<String> getAlgorithms (String serviceName)

  Returns a Set of String objects containing the names of all available algorithms or types for the specified Java cryptographic service (e.g., Signature , MessageDigest , Cipher , Mac , KeyStore ). Returns an empty set if there is no provider that supports the specified service or if serviceName is null . For a complete list of Java cryptographic services, please see the Moved out of a link with destination https://docs.oracle.com/pls/topic/lookup?ctx=javase20&id=security_guide_jca.Moved to a link with destination https://docs.oracle.com/pls/topic/lookup?ctx=javase21&id=security_guide_jca.Java Cryptography Architecture (JCA) Reference Guide. Note: the returned set is immutable.

  Parameters:

  serviceName - the name of the Java cryptographic service (e.g., Signature , MessageDigest , Cipher , Mac , KeyStore ). Note: this parameter is case-insensitive.

  Returns:

  a Set of String objects containing the names of all available algorithms or types for the specified Java cryptographic service or an empty set if no provider supports the specified service.

  getProperty

  public static String getProperty (String key)

  Gets a security property value.

  First, if there is a security manager, its checkPermission method is called with a java.security.SecurityPermission("getProperty."+key) permission to see if it's ok to retrieve the specified security property value.

  Parameters:

  key - the key of the property being retrieved.

  Returns:

  the value of the security property corresponding to , or null if there is no property with that key.

  Throws:

  SecurityException - if a security manager exists and its SecurityManager.checkPermission(java.security.Permission) method denies access to retrieve the specified security property value

  NullPointerException - is if key is null
