「Cisco Type 7 密码加密解密」是什么？What is the Cisco Type 7 Password Encoder / Decoder tool?
把 Cisco 配置里的 "password 7" 密文还原成明文，或把明文编码成 Type 7 格式；可一次粘贴整段配置，自动找出所有 Type 7 密码。Decode Cisco "password 7" strings back to plain text or encode plain text as Type 7; paste a whole config to find and decode every Type 7 password at once.
如何使用「Cisco Type 7 密码加密解密」？How do I use the Cisco Type 7 Password Encoder / Decoder?
解密：粘贴 Type 7 密文（例如 0822455D0A16）或整段 running-config，下方列出明文；加密：切换到「加密」，输入明文并选择种子（0–15）。0822455D0A16 解密后是 cisco。Decode: paste a Type 7 string (e.g. 0822455D0A16) or a whole running-config to list the plain text; Encode: switch to Encode, enter text and pick a seed (0–15). 0822455D0A16 decodes to cisco.
Type 7 是加密吗？安全吗？Is Type 7 real encryption?
不是。Type 7 只是用固定密钥表做的简单异或混淆，任何人都能瞬间还原，只能防止被旁人一眼看到。Cisco 建议使用 enable secret（Type 5/8/9）这类不可逆哈希。No. Type 7 is a simple XOR against a fixed key table that anyone can reverse instantly — it only stops shoulder-surfing. Cisco recommends irreversible hashes such as enable secret (Type 5/8/9).
同一个密码为什么会得到不同的密文？Why does the same password give different strings?
开头两位是随机种子（00–15），决定从密钥表哪个位置开始异或，所以同一密码可以有 16 种不同写法，解密结果都一样。The first two digits are a seed (00–15) that sets where XOR starts in the key table, so one password has 16 valid encodings that all decode the same.
