我正在尝试使用JarSigner对具有XMSS签名的.jar文件进行签名。
使用JCA/JCE的Provider量子后密码学BouncyCastle,可以以编程方式(example)生成XMSS和XMSSMT密钥对。
据我所知,要使用JarSigner,至关重要的是提供一个KeyStore和该条目的别名,该别名要使用以下代码签名:jarsigner -keystore myKeystore -storetype JKS -storepass password -keypass password myjarfile.jar keystoreEntryAlias
KeyStore条目包含Public / Secret KeyPair及其关联X.509证书。
使用JarSigner签名Jar文件的“正常”方式如下:
keytool -genkeypair -alias keystoreEntryAlias -keyalg RSA -sigalg SHA256withRSA -dname CN=MyCompanyName -storetype JKS -keypass password -keystore mykeystore.jks -storepass password
)jarsigner -keystore mykeystore.jks -storetype jks -storepass passeword -keypass password myjarfile.jar keystoreEntryAlias
)对.jar进行签名从理论上讲,为了使用XMSS密钥对文件签名,我有两种可能性:
jarsigner -keystore mykeystore -alias xmss
对文件进行签名。-providerclass org.bouncycastle.pqc.jcajce.provider.BouncyCastlePQCProvider
和-providerpath C:\Path\to\BouncyCastle\provider\bcprov-jdk15on-160.jar
),然后使用使用JarSigner的密钥库条目可悲的是,我遇到了两种可能性的问题:
我的问题现在是:
有人知道使用XMSS / XMSSMT和JarSigner签名.jar文件的方法吗,并且可以提供关于他/她做对了什么我做错了的详细解释? 或者,如果我对以上提到的任何内容有错,请提供更正并指出解决方法?
更新1 :我现在可以使用另一个X509CertificateGenerator(源代码位于[X509CertificateGenerator]的底部)和从here,here和{ {3}},以便使用BouncyCastle提供的RSA(在底部[RSA_JarSigner]底部签名的源代码)成功地对jar文件进行签名 以编程方式。
如果我尝试使用与RSA签名相同的方案来与XMSS或XMSSMT签名,则会遇到JarSignerException: Error in signer materials
引起的NoSuchAlgorithmException: unrecognized algorithm name: XMSS
(XMSS / XMSSMT源代码位于底部[SignXMSS] [SignXMSSMT]。
希望有人可以帮助我找出问题所在!
更新2 :似乎生成的XMSS(或XMSSMT)证书的问题是由于签名算法(即SHA256withXMSS)的条目作为ASN1ObjectIdentifier传递的事实所致。该系统还未知。因此,我进行了一些研究,以查看BouncyCastle是否并非偶然地在某处放置了XMSS证书生成器。.Bingo,here是一个!
我稍微缩短了代码,并提出了1个生成器和1个验证器(源代码位于[XMSSGen] [XMSSVer]的底部)。
生成器tho给我与其他方法(例如[X509CertificateGenerator])相同的证书。
验证者可悲地提示我这个难看的错误:Exception in thread "main" java.security.spec.InvalidKeySpecException: java.lang.ClassCastException: org.bouncycastle.asn1.DLSequence cannot be cast to org.bouncycastle.asn1.ASN1Integer
at org.bouncycastle.pqc.jcajce.provider.xmss.XMSSKeyFactorySpi.engineGeneratePrivate(Unknown Source)
at java.base/java.security.KeyFactory.generatePrivate(KeyFactory.java:384)
at BCXMSSCertificateVerifyer.verifyCertificate(BCXMSSCertificateVerifyer.java:32)
at BCXMSSCertificateTester.main(BCXMSSCertificateTester.java:23)
也许有人对它的来源/解决方法有所了解。为了查看BC是否可以与自己创建的XMSS证书一起使用。
编辑:验证程序的一个问题:PrivateKey privKey = keyFactory.generatePrivate(new PKCS8EncodedKeySpec(keyBytes));
为什么我们需要私钥来验证证书?没有任何意义-只需将其删除即可使用^^(至少应该如此)
更新3 :我终于设法使验证程序正常工作,因此我目前能够生产和验证XMSS证书。我还能够将XMSS密钥对和包含公钥的证书存储在密钥库中。尽管我仍然无法使用任何.jar文件签名。
现在有些奇怪:我可以使用BC XMSS密钥对(当然,这就是它们的用途)进行签名(如果我保存它们的话)(或者至少是私钥,因为他是必需的)签名),然后重新加载以再次签名。无论是将它们存储在KeyStore中并进行检索,还是将密钥作为编码的字节保存到文件中并再次加载它们,都不会。 (如果您对代码感兴趣,请发表评论,我会在此处发布)
我的建议是:由于XMSS签名方案要求保存一个状态(已使用的OTS的状态),因此在再次加载(无论是从KeyStore还是从文件不加载)时,都无法从PrivateKey中检索到该状态。物质),因此不能用来与某物进行签名。

答案 0 :(得分:0)
TL; DR:无法使用PQC签名.jar文件,例如BC使用内置的JarSigner提供的XMSS等签名方案。但是,可以先注册一个JarSigner,然后再注册。
尽管Oracle通过JCA / JCE为BC等加密提供程序提供了现成的集成,但是JarSigner既不使用这些注册提供程序也不进行签名或验证。 考虑到JarSigner:受支持的算法是硬编码的,因此无法扩展。
将JarSigner与BC Provider一起使用的唯一方法是完全重建它。但是,不建议这样做。
对于那些不怕劫持jdk源代码的人,您的项目必须“覆盖” jdk中的以下类:
因此,将原始代码复制粘贴到您的项目中,并删除所有您劫持的类的导入,这样将采用“自定义”类而不是正式类。
注意:上面提到的大多数类都可以在java.base模块中找到,尽管有些在jdk.jartool模块中(例如JarSigner本身)。
克隆了jdk的必要部分以使JarSigner正常工作之后,您最终可以继续以for the moment it seems like XMSS has some major problems的形式实现BC提供程序以及PQC签名方案(尤其是XMSSMT和SPHINCS)的支持。
请注意,对于签名的jar文件的the verification,JarVerifier采用签名块文件的文件扩展名,而是检查其.RSA,.DCA或.EC。因此,您将必须添加.XMSS .XMSSMT .SPHINCS256等。还必须告诉parseSignedData方法中的PKCS7类使用BC证书生成器。 我也忘记了其他一些更改(例如AlgorithmID),但是一旦完成所有必要的步骤,您的JarSigner就可以使用BC签名和验证.jar文件,除了使用“正常”的RSA DCA和EC签名和验证。
遗憾的是,尽管我将尝试回答尽可能多的问题,但我将无法与您分享最终的源代码。
