签名算法的算法约束检查失败：SHA256WithRSAEncryption

Question

有时，当服务器尝试使用 https 连接其他服务时，我一直注意到以下错误。 要采取什么措施来解决这个问题。 有趣的是，它只发生在少数服务器上。

Answer 1

谢谢大家，但我找到了这个问题的答案。 Had an older version of bouncy castle jar, after upgrading the the jar bcprov-jdk15on-1.58.jar, the "Algorithm constraints check failed on signature algorithm: SHA256WithRSAEncryption" error is no longer occurring.

Answer 2

请查看受影响服务器中与 TLS 相关的 java 配置，SDK 使用安全属性jdk.certpath.disabledAlgorithms和jdk.tls.disabledAlgorithm在 TLS 协议协商期间禁用算法，并且可能已禁用SHA256WithRSAEncryption 。

您可以在 Java 安装的<install_dir>/jre/lib/security/java.security文件中找到这些属性的值。

请考虑阅读这篇相关文章，它适用于 IBM SDK 8，但对于其他 SDK 版本和供应商，描述的行为应该相同或非常相似。

此外，在受影响的服务器中运行程序时，请考虑启用值为certpath或all的java.security.debug环境属性：

-Djava.security.debug=certpath

它将为您提供有关正在发生的事情以及 Java 抱怨该算法的原因的指导和有价值的信息。
