PBEWITHSHA256AND128BITAES-CBC-BC creating java.sec

2020-07-06 06:17发布

问题:

We have an application that uses Bouncy Castle to encrypt data using PBEWITHSHA256AND128BITAES-CBC-BC algorithm. It works fine on Ubuntu running OpenJDK 1.7. But when when we move it to RedHat 6.4 also running OpenJDK 1.7, we get the following exception:

java.security.NoSuchAlgorithmException

Any thoughts on what could be causing this. How can we add PBEWITHSHA256AND128BITAES-CBC-BC algorithm to RedHat 6.4?

p.s. the application is running in JBoss.

private String cryptoAlgorithm = "PBEWITHSHA256AND128BITAES-CBC-BC";

Security.addProvider(new BouncyCastleProvider());

// load passPhrase from configured external file to char array.
char[] passPhrase = null;
try {
    passPhrase = loadPassPhrase(passPhraseFile);
} catch (FileNotFoundException e) {
    throw BeanHelper.logException(LOG, methodName, new EJBException("The file not found: " + passPhraseFile, e));
} catch (IOException e) {
    throw BeanHelper.logException(LOG, methodName, new EJBException("Error in reading file: " + passPhraseFile, e));
}

PBEKeySpec pbeKeySpec = new PBEKeySpec(passPhrase);

try {
    SecretKeyFactory secretKeyFactory = SecretKeyFactory.getInstance(cryptoAlgorithm);
    SecretKey newSecretKey = secretKeyFactory.generateSecret(pbeKeySpec);
    return newSecretKey;
} catch (NoSuchAlgorithmException e) {
    throw BeanHelper.logException(LOG, methodName, new EJBException("The algorithm is not found: " + cryptoAlgorithm, e));
} catch (InvalidKeySpecException e) {
    throw BeanHelper.logException(LOG, methodName, new EJBException("The key spec is invalid", e));
}

回答1:

Do you have the BouncyCastle provider JAR (e.g. bcprov-jdk15on-149.jar) in your classpath?

I tested your scenario with a minimal CentOS 6.4 (64-bit) installation, OpenJDK 1.7 and BouncyCastle 1.49, and found no issues with it.

I placed the JAR in the JRE lib/ext directory:

/usr/lib/jvm/java-1.7.0-openjdk.x86_64/jre/lib/ext

I try to confirm your issue and looks like problem in your environment. Here is sample of code i successfully run on clean OpenJDK 1.7, 1.6, Oracle JDK 1.7 and 1.6

$ java -version
java version "1.7.0_19"
OpenJDK Runtime Environment (rhel-2.3.9.1.el6_4-x86_64)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode):

Command line: java -cp bcprov-jdk15on-149.jar:. Test

Output: OK

import org.bouncycastle.jce.provider.BouncyCastleProvider;

import javax.crypto.SecretKey;
import javax.crypto.SecretKeyFactory;
import javax.crypto.spec.PBEKeySpec;
import java.security.NoSuchAlgorithmException;
import java.security.Security;
import java.security.spec.InvalidKeySpecException;

public class Test {
    public static void main(String[] args) throws Exception{
        String cryptoAlgorithm = "PBEWITHSHA256AND128BITAES-CBC-BC";
        Security.addProvider(new BouncyCastleProvider());

        char[] passPhrase = null;
        passPhrase = "12321".toCharArray();
        PBEKeySpec pbeKeySpec = new PBEKeySpec(passPhrase);
        try {
            SecretKeyFactory secretKeyFactory = SecretKeyFactory.getInstance(cryptoAlgorithm, "BC");
            SecretKey newSecretKey = secretKeyFactory.generateSecret(pbeKeySpec);
            assert newSecretKey != null;
            System.out.println("OK");
        } catch (NoSuchAlgorithmException e) {
            System.out.println("The algorithm is not found: " + cryptoAlgorithm);
        } catch (InvalidKeySpecException e) {
            System.out.println("The key spec is invalid");
        }
    }
}

Try to run that program on your environment. BouncyCastle jar you can download from here http://downloads.bouncycastle.org/java/bcprov-jdk15on-149.jar

I guess the order of the security providers is different in both environments.

for (Provider provider : Security.getProviders())
{
    System.out.println("Name: " + provider.getName() + " Version: " + provider.getVersion());
}

you can try to insert the bouncy castle provider at a specific position in the chain of providers. Here for example at the first position, if no other security provider is used this should not lead into problems.

Security.insertProviderAt(new BouncyCastleProvider(), 1);

the use of a specific provider for an algorithm is not recommended

SecretKeyFactory.getInstance(cryptoAlgorithm, provider)
