Question

我正在玩BouncyCastle 1.46令我惊讶的是，下面的片段中的捕获块经常被绊倒。

Security.addProvider(new BouncyCastleProvider());

final Set<String> found = new HashSet<String>();
final Set<String> missing = new HashSet<String>();

final DefaultSignatureAlgorithmIdentifierFinder finder = new DefaultSignatureAlgorithmIdentifierFinder();
for (Service service : new BouncyCastleProvider().getServices()) {
    if ("Signature".equals(service.getType())) {
        final String algorithm = service.getAlgorithm();
        try {
            finder.find(algorithm);
            found.add(algorithm);
        } catch (IllegalArgumentException ex) {
            missing.add(algorithm);
        }
    }
}

System.out.println("Found: " + found);
System.out.println("Missing: " + missing);

我似乎无法通过Finder使用大多数算法，即使存在提供这些算法的服务。我做错了什么？

更新我已经更改了一些代码以更好地说明问题。可能感兴趣的是我使用的是BouncyCastle的JDK1.5版本。上面的代码给出了这个输出：

我认为DefaultSignatureAlgorithmIdentifierFinder是bcmail API的一部分。它返回此API识别的算法标识符。（检查Cryptographic Message Syntax）另一方面，弹性种姓提供者提供更多算法。您可以检查已识别算法被硬编码的DefaultSignatureAlgorithmIdentifierFinder的来源：

干杯！

Answer 2

您是否将BouncyCastle添加到安全提供程序？你可以用这一行来做到这一点：

Security.addProvider(new BouncyCastleProvider());

Answer 3

您可以通过两个步骤将Bouncy Castle添加到Java平台上的安全提供程序中：

1. 将BC librarys（目前为bcpkix-jdk15on-149.jar，bcprov-jdk15on-149.jar）复制到目录 $ JAVA_HOME / jre / lib / ext /

2. 注册BC提供商：编辑文件 $ JAVA_HOME / jre / lib / security / java.security 并在行

下

security.provider.1=sun.security.provider.Sun

添加您的BC提供商

security.provider.2=org.bouncycastle.jce.provider.BouncyCastleProvider

更改其他提供商的数量。整个提供者块应类似于：

security.provider.1=sun.security.provider.Sun
security.provider.2=org.bouncycastle.jce.provider.BouncyCastleProvider
security.provider.3=sun.security.rsa.SunRsaSign
security.provider.4=sun.security.ec.SunEC
security.provider.5=com.sun.net.ssl.internal.ssl.Provider
security.provider.6=com.sun.crypto.provider.SunJCE
security.provider.7=sun.security.jgss.SunProvider
security.provider.8=com.sun.security.sasl.Provider
security.provider.9=org.jcp.xml.dsig.internal.dom.XMLDSigRI
security.provider.10=sun.security.smartcardio.SunPCSC

Answer 4

这个答案与BouncyCastle没有直接关系。但是，我认为这对其他人有用：

在我的情况下，我使用的是SpongyCastle。我遇到了类似的问题： org.e.h.p：无法创建签名者：Provider SC不提供SHA256WITHRSA 在org.e.h.a.a.a（SourceFile：101）

事实证明，proguard正在删除一些必需的类。在proguard配置文件中添加以下内容后： -keep class org.spongycastle。** {*; }

问题得到了解决。

BouncyCastle没有找到它提供的算法？
