返回值: 此方法返回一个 描述 供应商及其服务的信息。
下面是一些例子来说明 getInfo() 方法:
例1:
// Java program to demonstrate // get() method import java.security.*; import java.util.*; public class GFG1 { public static void main(String[] argv) throws Exception { try { // creating the object of KeyPairGenerator KeyPairGenerator sr = KeyPairGenerator.getInstance( "DSA" , "SUN" ); // getting the Provider of the KeyPairGenerator sr // by using method getProvider() Provider provider = sr.getProvider(); // getting the info String info = provider.getInfo(); // printing the string info System.out.println( "info : " + info); } catch (NoSuchAlgorithmException e) { System.out.println( "Exception thrown : " + e); } } } |
输出:
info : SUN (DSA key/parameter generation; DSA signing; SHA-1, MD5 digests; SecureRandom; X.509 certificates; JKS & DKS keystores; PKIX CertPathValidator; PKIX CertPathBuilder; LDAP, Collection CertStores, JavaPolicy Policy; JavaLoginConfig Configuration)
例2:
// Java program to demonstrate // get() method import java.security.*; import java.util.*; public class GFG1 { public static void main(String[] argv) throws Exception { try { // creating the object of SecureRandom SecureRandom sr = SecureRandom.getInstance( "SHA1PRNG" ); // getting the Provider of the SecureRandom sr // by using method getProvider() Provider provider = sr.getProvider(); // getting the info String info = provider.getInfo(); // printing the string info System.out.println( "info : " + info); } catch (NoSuchAlgorithmException e) { System.out.println( "Exception thrown : " + e); } } } |
输出:
info : SUN (DSA key/parameter generation; DSA signing; SHA-1, MD5 digests; SecureRandom; X.509 certificates; JKS & DKS keystores; PKIX CertPathValidator; PKIX CertPathBuilder; LDAP, Collection CertStores, JavaPolicy Policy; JavaLoginConfig Configuration)
