这个 getAlgorithm() 方法 JAVA安全签名 类用于返回此签名对象的算法名称。 语法:
null
public final String getAlgorithm()
返回值: 此方法返回此签名对象的算法名称。 下面是演示getAlgorithm()方法的示例: 例1:
JAVA
// Java program to demonstrate // getAlgorithm() method import java.security.*; import java.util.*; public class GFG1 { public static void main(String[] argv) { try { // creating the object of Signature Signature sr = Signature.getInstance( "SHA1withDSA" ); // getting 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); } } } |
输出:
Algorithm: SHA1withDSA
例2:
JAVA
// Java program to demonstrate // getAlgorithm() method import java.security.*; import java.util.*; public class GFG1 { public static void main(String[] argv) { try { // creating the object of Signature Signature sr = Signature.getInstance( "NONEwithDSA" ); // getting 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); } } } |
输出:
Algorithm: NONEwithDSA
