Purpose: This page documents the SSH key provided for permanent server access setup. The actual private key material is intentionally not re-published in full here for security. Use the key only on trusted machines.
用途： 本页记录为永久服务器访问而提供的 SSH 密钥处理方式。出于安全考虑，完整私钥内容不在此重新公开。仅在可信机器上使用。
The text block starting with -----BEGIN OPENSSH PRIVATE KEY----- is an OpenSSH Ed25519 private key (comment: redymail). It is a secret credential that proves your identity to the server.
以 -----BEGIN OPENSSH PRIVATE KEY----- 开头的文本块是 OpenSSH Ed25519 私钥（注释：redymail）。它是证明你身份的秘密凭证，相当于服务器的“私人钥匙”。
Step 1: Never share the private key in chat, email, or public websites. Only store it on your own computer in a protected file.
步骤 1： 永远不要在聊天、邮件或公开网站分享私钥。只保存在你自己电脑的受保护文件中。
Step 2: On your Mac, create the file and set strict permissions:
步骤 2： 在你的 Mac 上创建文件并设置严格权限：
mkdir -p ~/.ssh chmod 700 ~/.ssh # 把私钥内容粘贴进去（用文本编辑器或 cat） nano ~/.ssh/id_ed25519_redymail # 保存后执行： chmod 600 ~/.ssh/id_ed25519_redymail
Step 3: Test the key (replace with actual server if needed):
步骤 3： 测试密钥（根据需要替换服务器）：
ssh -i ~/.ssh/id_ed25519_redymail -p 2222 root@165.154.238.214 "echo ok"
Step 4: To add a new public key permanently (what was done for Grok): append the public key line to /root/.ssh/authorized_keys on the server. No need to re-send private keys in the future.
步骤 4： 要永久添加新公钥（本次已为 Grok 完成）：把公钥那一行追加到服务器的 /root/.ssh/authorized_keys。以后不用再发私钥。
Public key grok-sandbox-lilycase-dual has been permanently added to authorized_keys on the 214 server. Future operations can use the corresponding private key without further human intervention.
公钥 grok-sandbox-lilycase-dual 已永久写入 214 服务器的 authorized_keys。以后操作可直接使用对应私钥，无需再麻烦人类。
