Java Signature getAlgorithm() method with Examples

The getAlgorithm() method of java.security.Signature class is used to return the name of the algorithm for this signature object.

Syntax:

public final String getAlgorithm()

Return Value: This method returns the name of the algorithm for this signature object.

Below are the examples to illustrate the getAlgorithm() method:

Example 1:

            // creating the object of Signature
            Signature sr = Signature.getInstance("SHA1withDSA");
  
            // geting the Algorithm
            // by using method getAlgorithm()
            String algo = sr.getAlgorithm();
  
            // printing the string algo
            System.out.println("Algorithm: " + algo);
        }
  
        catch (NoSuchAlgorithmException e) {
  
            System.out.println("Exception thrown : " + e);
        }
    }
