加密技术PBewithSHA256和128位AESCBC创建java。安全RedHat 6.4上的NoSuchAlgorithmException

Question

我们有一个应用程序，它使用Bouncy Castle来使用PBEWITHSHA256AND128BITAES-CBC-BC算法加密数据。它在Ubuntu运行OpenJDK 1.7时运行良好。但是当我们将它移动到RedHat 6.4同时运行OpenJDK 1.7时，我们会得到以下异常：

java.security.NoSuchAlgorithmException

有没有想过是什么导致了这一切。我们如何将PBEWITHSHA256AND128BITAES-CBC-BC算法添加到RedHat 6.4中

p.s.应用程序正在^{中运行

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));
}

（右侧6.4）

#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)

（在Ubuntu 12.04上）

#java version "1.7.0_15"
OpenJDK Runtime Environment (IcedTea7 2.3.7) (7u15-2.3.7-0ubuntu1~12.04)

Answer 1

我猜在这两种环境中，安全提供者的顺序是不同的

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

您可以尝试在提供者链中的特定位置插入bouncy castle提供者。例如，在第一个位置，如果没有使用其他安全提供程序，则不会导致问题

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

不建议对算法使用特定的提供程序

SecretKeyFactory.getInstance(cryptoAlgorithm, provider)

见：Java ™ Cryptography Architecture(JCA) Reference Guide

Answer 2

我试图确认您的问题，看起来您的环境中存在问题。下面是我在干净的OpenJDK1.7、1.6、OracleJDK1.7和1.6上成功运行的代码示例

$ 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):

命令行：java -cp bcprov-jdk15on-149.jar:. Test

输出：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");
        }
    }
}

尝试在您的环境中运行该程序。BouncyCastle jar您可以从这里下载http://downloads.bouncycastle.org/java/bcprov-jdk15on-149.jar

Answer 3

您的类路径中是否有BouncyCastle提供程序JAR（例如bcprov-jdk15on-149.JAR）

我使用最低限度的CentOS 6.4（64位）安装、OpenJDK 1.7和BouncyCastle 1.49测试了您的场景，没有发现任何问题

我将JAR放在JRE lib/ext目录中：

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