SSH 密钥类型在 SSH 中，常见的密钥类型包括以下几种：
RSA：这是最早的 SSH 密钥类型之一，使用 RSA 加密算法。RSA 密钥在 SSH 中被广泛使用，并且是许多 SSH 工具和协议的默认密钥类型。
DSA：这是另一种早期的 SSH 密钥类型，使用 DSA 加密算法。DSA 密钥已被广泛使用，但现在已不建议使用。
ECDSA：这是一种基于椭圆曲线加密算法的 SSH 密钥类型，通常比 RSA 和 DSA 密钥更安全和高效。
ed25519：这是一种基于椭圆曲线加密算法的公钥加密方案，它被广泛应用于 SSH 密钥认证。ed25519 密钥具有更高的安全性和更好的性能...

事情起因是我闲着无聊在拼多多上买了十把美工刀，得力。
我手上也有一把得力的，和商品选项上的图片也是一样的，结果还是翻车了。
结果拿着证据找了拼多多客服，拼多多客服判定店铺违规，并退了钱。
结果半夜我脑抽，忽然想会不会是店家被误会了，真的有这样长相的一把刀?于是我成功在淘宝旗舰店找到了一把类似的的美工刀，当时心想，我良心道德都没了…
拿着旗舰店的买家秀对比了半天，确定我还真的没误会这个店家，那丫就是个卖假货的。
我刚拿到手时，发现有几点不对：
使用的材质不对，得力的美工刀使用的不锈钢材质有拉丝抛光，而这把美工刀使用的不锈钢材质是镜面的。
美工刀的做工虽然算不上差，但是正面出现不规则的加工...

为什么要使用域名？域名可以保证使用时候比较舒服，因为所有服务都可以使用同一个 80 端口或者 443 端口，而不需要每个服务单独占用一个独立的非标准端口。
这样的情况下，http 服务器区分服务的办法，只能以来域名。
并非一定需要购买域名，例如范例中的 *.lab.com，只需要在 hosts 文件中加入映射即可访问。
