我在 Ubuntu 20.04 上使用 Squid 4.13 已經有大約一週的時間了。
我最新的（希望也是最後一個）問題是這樣的：
致命：沒有為 HTTPS_port 設定有效的簽章憑證
這是我的台詞：
https_port 0.0.0.0:3128 intercept ssl-bump generate-host-certificates=on dynamic_cert_mem_cache_size=4MB cert=/usr/local/squid/etc/rootCA.crt key=/usr/local/squid/etc/rootCA.key options=SINGLE_DH_USE,SINGLE_ECDH_USE tls-dh=/usr/local/squid/etc/dhparam.pem
我一直在四處尋找（至少感覺如此），甚至魷魚自己的維基（https://wiki.squid-cache.org/ConfigExamples/Intercept/SslBumpExplicit）是維爾德？因為在開始時他們展示瞭如何處理 .pem 文件，但在文檔末尾展示了示例行，他們談論的是 .crt 和 .key 以及完全不同的 .pem 文件。
我唯一改變的就是將位數提高到 4096
所以，我又迷路了！有人知道他們在說什麼嗎？什麼是正確的格式以及如何做到這一點......啊！幫助？
編輯：這是我正在使用的“標準”配置：

/etc/squid/conf.d 中包含的設定是一個名為 debian.conf 的檔案：
#
# Squid configuration settings for Debian
#
# Logs are managed by logrotate on Debian
logfile_rotate 0
# For extra security Debian packages only allow
# localhost to use the proxy on new installs
#
#http_access allow localnet
按照要求：

答案1
解決方案的一部分是 ID 10 T 問題，顯然憑證有錯誤，即使您測試說它沒問題，但在建立新憑證後它就起作用了。
