java - Bouncy CaSTLe，NoSuchMethodError(org.bouncycaSTLe.asn1.ASN1Integer)

Question

我对加密/证书完全陌生，并尝试使用 Bouncy CaSTLe 库生成证书。看看他们的一些示例代码，这是我到目前为止所拥有的:

                keyPair.getPublic());

        ContentSigner signer = new JcaContentSignerBuilder("SHA1WithRSA").setProvider("BC").build(keyPair.getPrivate());

        return new JcaX509CertificateConverter().setProvider("BC").getCertificate(certBldr.build(signer));
    }

        JcaX509ExtensionUtils extUtils = new JcaX509ExtensionUtils();

        certBldr.addExtension(Extension.authorityKeyIdentifier, false, extUtils.createAuthorityKeyIdentifier(caCert))

                .addExtension(Extension.keyUsage, true, new KeyUsage(KeyUsage.digitalSignature | KeyUsage.keyEncipherment));

        ContentSigner signer = new JcaContentSignerBuilder("SHA1withRSA").setProvider("BC").build(caKey);

        return new JcaX509CertificateConverter().setProvider("BC").getCertificate(certBldr.build(signer));
    }
}

我的 pom 有各种 Bouncy CaSTLe 库和最新的 itext:

有人知道为什么吗？

发生这种情况是因为使用了不同的版本(1.56 和 1.46)。 1.47版本之后，many parts of the API have changed .

我可以运行您的代码，将我的 pom.xml 更改为仅使用版本 1.56:

<dependency>
    <groupId>org.bouncycastle</groupId>
    <artifactId>bcprov-jdk15on</artifactId>
    <version>1.56</version>
</dependency>
<dependency>
    <groupId>org.bouncycastle</groupId>
    <artifactId>bcmail-jdk15on</artifactId>
    <version>1.56</version>
</dependency>

这是运行您的问题中的代码的最小库集。当然，如果您的应用程序需要使用其他库(bcpg、bcprov-ext 等)，您可以相应地包含它们(但我建议您选择版本 >= 1.55，以避免这些混合版本问题)

注意: bcmail 依赖于 bccpkix 和 bcprov，所以实际上只有 bcmail pom.xml 中需要 >
