如何为 elytron 生成屏蔽密码？

Question

我想用掩码密码替换我在 wildfly-config.xml 中使用的明文密码，这似乎在 WildFly 18 中受支持。我试过使用 elytron-tool 生成屏蔽密码：

./elytron-tool.sh mask --salt 12345678 --iteration 12 --secret password
MASK-2FVkvIpoGRstP19QEZ76qE;12345678;12

然后我将哈希 ("2FVkvIpoGRstP19QEZ76qE") 转换为 base64 并添加到 wildfly-config.xml

<credentials>
        <masked-password iteration-count="12" salt="12345678" masked-password="MkZWa3ZJcG9HUnN0UDE5UUVaNzZxRQ=="/>
</credentials>
<sasl-mechanism-selector selector="DIGEST-MD5"/>

但是它失败了：

Caused by: java.security.spec.InvalidKeySpecException: javax.crypto.IllegalBlockSizeException: Input length must be multiple of 8 when decrypting with padded cipher

所以看来我生成屏蔽密码的过程是错误的。你能建议任何 tool/shell 命令来生成有效的掩码密码吗？非常感谢

您可以在 Jboss' 开发者博客中找到生成屏蔽密码的示例代码：https://developer.jboss.org/people/aabdelsa/blog/2019/09/05/support-for-masked-passwords-in-the-client-xml-configuration 希望对你有帮助
