docs: Gets a specified property for an algorithm. The algorithm name
  should be a standard name. See the <a href=
  "{@docRoot}openjdk-redirect.html?v=8&path=/technotes/guides/security/StandardNames.html">
  Java Cryptography Architecture Standard Algorithm Name Documentation</a>
  for information about standard algorithm names.
  
  One possible use is by specialized algorithm parsers, which may map
  classes to algorithms which they understand (much like Key parsers
  do).
  
  @param algName the algorithm name.
  
  @param propName the name of the property to get.
  
  @return the value of the specified property.
  
  @deprecated This method used to return the value of a proprietary
  property in the master file of the "SUN" Cryptographic Service
  Provider in order to determine how to parse algorithm-specific
  parameters. Use the new provider-based and algorithm-independent
  <code>AlgorithmParameters</code> and <code>KeyFactory</code> engine
  classes (introduced in the J2SE version 1.2 platform) instead.
