DH密钥大小必须是64的倍数，并且只能在512到2048(含)范围内 [英] DH key size must be multiple of 64, and can only range from 512 to 2048 (inclusive)

问题描述

我有一个设置，其中我正在通过ANT中的sshexec任务在Solaris Server上从Jenkins执行构建.

I have a set-up in which I am executing a build from Jenkins on a Solaris Server connecting via sshexec task in ANT.

在触发构建时，它抛出以下错误:

On trigerring the build, it is throwing below error:

com.jcraft.jsch.JSchException:Session.connect: java.security.InvalidAlgorithmParameterException:DH密钥大小必须为 64的倍数，并且只能在512到2048(含)之间变化.这 不支持特定的密钥大小2047.

com.jcraft.jsch.JSchException: Session.connect: java.security.InvalidAlgorithmParameterException: DH key size must be multiple of 64, and can only range from 512 to 2048 (inclusive). The specific key size 2047 is not supported.

经过一些Google搜索，我知道可以通过更新到Java 8来解决它.但是，这样做还是没有成功.

After some google search, I came to know that it might be fixed by updating to Java 8. I did that, however, still no success.

任何人都可以让我知道如何解决此问题吗?

Can anyone please let me know how to fix it?

推荐答案

我们的解决方法:

Security.insertProviderAt(new BouncyCastleProvider(), 1)

我们直接使用Jsch 0.1.54连接到SFT服务器并看到:

we were using Jsch 0.1.54 directly to connect to an SFT server and saw:

java.security.InvalidAlgorithmParameterException:DH密钥大小必须是64的倍数，并且只能在512到4096(含)范围内.不支持特定的密钥大小2047

java.security.InvalidAlgorithmParameterException: DH key size must be multiple of 64, and can only range from 512 to 4096 (inclusive). The specific key size 2047 is not supported

• JDK-8164963:使用JSCH库升级JDK后，InvalidAlgorithmParameterException基本大小问题.
• DHGEX在Java 8下使用2048位密钥失败，但是在1024位密钥下成功

• JDK-8164963: InvalidAlgorithmParameterException prime size issue after JDK upgrade with JSCH libraries.
• DHGEX failing with 2048-bit key under Java 8, but succeeding with 1024-bit key
