java.security.Provider类的getInfo()方法用于返回提供程序及其服务的可读描述。这可能会返回带有相关链接的HTML页面。
用法:
public String getInfo()
返回值:此方法返回提供者及其服务的描述。
下面是说明getInfo()方法的示例:
范例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)
范例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)
