PBEWITHSHA256和128BITAES-CBC-BC在RedHat 6.4上创建java.security.NoSuchAlgorithmException
我们有一个应用程序，它使用PBEWITHSHA256AND128BITAES-CBC-BC算法使用Bouncy Castle对数据进行加密。它在运行OpenJDK 1.7的Ubuntu上运行良好。但是，当我们将它移到同时运行OpenJDK 1.7的RedHat 6.4上时，我们会得到以下异常：
java.security.NoSuchAlgorithmException
有没有想过是什么原因造成的。如何在RedHat 6.4中添加PBEWITHSHA256AND128BITAES-CBC-BC算法
p.s.应用程序在JBoss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));

您的类路径中是否有BouncyCastle提供者JAR (例如bcprov-jdk15on-149.jar)？
我使用最小的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：

我尝试确认您的问题，并且在您的环境中看起来有问题。下面是我在clean OpenJDK 1.7、1.6、Oracle JDK1.7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。您可以从此处http://downloads.bouncycastle.org/java/bcprov-jdk15on-149.jar下载BouncyCastle jar

我猜在这两个环境中，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());
}您可以尝试在提供程序链中的特定位置插入bouncy castle提供程序。例如，在第一个位置，如果没有使用其他安全提供商，这应该不会导致问题。
Security.insertProviderAt(new BouncyCastleProvider(), 1);不建议对算法使用特定的提供程序
