BouncyCastle没有找到它提供的算法？

Question

我正在玩BouncyCastle 1.46令我惊讶的是,下面片段中的陷阱经常被绊倒.

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.我究竟做错了什么？

更新我稍微更改了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:

我认为这DefaultSignatureAlgorithmIdentifierFinder是bcmail API的一部分.它返回此API识别的算法标识符.(检查加密消息语法)另一方面,弹性种姓提供者提供更多算法.您可以检查DefaultSignatureAlgorithmIdentifierFinder识别的算法硬编码的来源:
