  - toOID
```
public OBJECT_IDENTIFIER toOID()
                        throws java.security.NoSuchAlgorithmException
```
    Returns the object identifier for this algorithm.
    
    Throws:
    
    java.security.NoSuchAlgorithmException - If no OID is registered for this algorithm.
  - getParameterClass
```
public java.lang.Class getParameterClass()
```
    Deprecated. Call getParameterClasses() instead.
    
    The type of parameter that this algorithm expects. Returns null if this algorithm does not take any parameters. If the algorithm can accept more than one type of parameter, this method returns only one of them. It is better to call getParameterClasses().
  - getParameterClasses
```
public java.lang.Class[] getParameterClasses()
```
    The types of parameter that this algorithm expects. Returns null if this algorithm does not take any parameters.
  - isValidParameterObject
```
public boolean isValidParameterObject(java.lang.Object o)
```
    Returns true if the given Object can be used as a parameter for this algorithm.
    If null is passed in, this method will return true if this algorithm takes no parameters, and false if this algorithm does take parameters.
