无法在Openssl中加载引擎

我试图测试一个引擎，以便与一台计算机对话，但它失败得惊人：

$ openssl engine -t dynamic -pre ~/Downloads/engine_openhsmd.so -pre ID:openhsmd
                      -pre LIST_ADD:1 -pre LOAD -pre ADDRESS_CONN:150.162.56.205

我一行字都听不懂。错误的来源是什么？

引擎路径是一个参数，必须以参数名

作为前缀，因此路径：

。此外，路径必须是绝对路径，但一旦添加参数名称，产生的错误更容易读取

$ openssl engine -t dynamic -pre SO_PATH:/home/boppreh/Downloads/engine_openhsmd.so
     -pre ID:openhsmd -pre LIST_ADD:1 -pre LOAD -pre ADDRESS_CONN:150.162.56.205
