BouncyCastle does not find algorithms that it provides?

Question

I'm playing around with BouncyCastle 1.46 To my surprise, the catch-block in the snippet below is tripped quite often.

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);

I appear to be unable to use most of the algorithms through the Finder, even though Services exist that provide those algorithms. What am I doing wrong?

Update I've changed the code a little to illustrate the issue better. What might be of interest is that I am using the JDK1.5 version of BouncyCastle. The code above gives this output:

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

Answer 1

I think that DefaultSignatureAlgorithmIdentifierFinder is part of the bcmail API. It returns algorithm identifiers recognized by this API. (Check Cryptographic Message Syntax) On the other hand the bouncy castle provider provides more algorithms. You may check the source of DefaultSignatureAlgorithmIdentifierFinder where the recognized algorithms are hardcoded:

algorithms.put("MD2WITHRSAENCRYPTION", PKCSObjectIdentifiers.md2WithRSAEncryption);
algorithms.put("MD2WITHRSA", PKCSObjectIdentifiers.md2WithRSAEncryption);

Answer 2

This answer is not directly related to BouncyCastle. But, I thought this would be useful for others:

In my case, I was using SpongyCastle. I got a similar problem: org.e.h.p: cannot create signer: Provider SC does not provide SHA256WITHRSA at org.e.h.a.a.a(SourceFile:101)

It turned out that proguard was removing some of the required classes. After adding the following in proguard config file: -keep class org.spongycastle.** { *; }

the problem was resolved.

You can add Bouncy Castle to security providers on Your java platform in two steps:

1. Copy BC librarys (currently bcpkix-jdk15on-149.jar, bcprov-jdk15on-149.jar) to directory $JAVA_HOME/jre/lib/ext/

2. Register BC provider: edit file $JAVA_HOME/jre/lib/security/java.security and under line

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

add Your BC provider

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

Change numbers of rest providers. The whole block of providers should be similar to:

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

Did you add BouncyCastle to the security providers? You can do that with this line:

Security.addProvider(new BouncyCastleProvider());
