BouncyCastle找不到它提供的算法?

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 found = new HashSet(); final Set missing = new HashSet(); 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:

实测值:[RIPEMD256WithRSAEncryption,MD5WithRSAEncryption,MD2WithRSAEncryption,SHA384WithRSAEncryption,SHA224WITHECDSA,SHA384WITHDSA,SHA256WITHDSA,SHA512WithRSAEncryption,SHA512WITHDSA,RIPEMD160WithRSAEncryption,SHA224WithRSAEncryption,SHA256WITHECDSA,RIPEMD128WithRSAEncryption,SHA384WITHECDSA,SHA256WithRSAEncryption,SHA512WITHECDSA,SHA1WithRSAEncryption,SHA224WITHDSA]

缺失:[SHA1WITHECNR,NONEwithECDSA,ECDSA,SHA512withRSA / PSS,RIPEMD160WITHECDSA,RSA,GOST3410,SHA256WITHECNR,MD5withRSA / ISO9796-2,SHA1WITHCVC-ECDSA,SHA384withRSA / PSS,SHA1withRSA / PSS,MD4WithRSAEncryption,RSASSA-PSS,SHA512WITHECNR,SHA256WITHCVC-ECDSA ,SHA1withRSA / ISO9796-2,SHA224withRSA / PSS,SHA224WITHCVC-ECDSA,RAWRSASSA-PSS,SHA256withRSA / PSS,NONEWITHDSA,SHA384WITHECNR,RIPEMD160withRSA / ISO9796-2,DSA,ECGOST3410,SHA224WITHECNR,1.2.840.113549.1.1.10]

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的源代码,其中识别的算法是硬编码的:

干杯!

您是否将BouncyCastle添加到安全提供商? 你可以用这一行做到这一点:

 Security.addProvider(new BouncyCastleProvider()); 

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:

1.将BC库(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提供者:编辑文件$ JAVA_HOME / jre / lib / security / java.security并在线下

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

添加您的BC提供商

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

更改其他提供者的数量。 整个提供商块应类似于:

 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 

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

就我而言,我使用的是SpongyCastle。 我遇到了类似的问题:org.ehp:无法创建签名者:提供者SC不在org.ehaaa提供SHA256WITHRSA(SourceFile:101)

事实certificate,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。** {*; }

问题解决了。
