iOS逆向之三-authorized_keys ssh登陸越獄手機免驗證設置

默認狀況下使用ssh登陸到iPhone每次都是須要輸入密碼的，比較繁瑣，能夠配置ios的authorized_keys和電腦端的一致來簡化這個步驟

電腦配置

刪除 ~/.ssh/known_hosts文件的配置

known_hosts 的文件以下

➜  .ssh cat known_hosts  
192.168.8.220 ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC7ZyuWzvOD7ZvO4cvz+OI9npOmCLkqIPIEMUg+A0/TL3MxB+KGEC7XaEI4tZb/617w9sIJbH0LeXlwAb7be0lrLDntXnH9mQV0DcI94mfOmMKCZtzBcPiHqYVFiEXi4Gtdn2Ki8wH8s5EvIB+Xtad2ZCoR9KpDFxINw9SkMvxAK5zO6RkoQbe8EHKK2986d+QrnT39HfqymP744RhCABuSkGTyeIFBYJlqjUT+HocLfIrF4MBdQul4JJa7rcm7F3NDp+DLryAh6/yJRsXSlM2RcdkbvhD2Cvvd+YJCcD0LPht1Nibf91htvd2glUjoU4DpIUwd7RI8OvVH+QETXjO9
192.168.8.215 ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC7ZyuWzvOD7ZvO4cvz+OI9npOmCLkqIPIEMUg+A0/TL3MxB+KGEC7XaEI4tZb/617w9sIJbH0LeXlwAb7be0lrLDntXnH9mQV0DcI94mfOmMKCZtzBcPiHqYVFiEXi4Gtdn2Ki8wH8s5EvIB+Xtad2ZCoR9KpDFxINw9SkMvxAK5zO6RkoQbe8EHKK2986d+QrnT39HfqymP744RhCABuSkGTyeIFBYJlqjUT+HocLfIrF4MBdQul4JJa7rcm7F3NDp+DLryAh6/yJRsXSlM2RcdkbvhD2Cvvd+YJCcD0LPht1Nibf91htvd2glUjoU4DpIUwd7RI8OvVH+QETXjO9
複製代碼

好比說你的iPhone手機IP是192.168.8.215，那麼就把這一項的配置刪除，刪除以後的配置以下便可。

➜  .ssh cat known_hosts  
192.168.8.220 ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC7ZyuWzvOD7ZvO4cvz+OI9npOmCLkqIPIEMUg+A0/TL3MxB+KGEC7XaEI4tZb/617w9sIJbH0LeXlwAb7be0lrLDntXnH9mQV0DcI94mfOmMKCZtzBcPiHqYVFiEXi4Gtdn2Ki8wH8s5EvIB+Xtad2ZCoR9KpDFxINw9SkMvxAK5zO6RkoQbe8EHKK2986d+QrnT39HfqymP744RhCABuSkGTyeIFBYJlqjUT+HocLfIrF4MBdQul4JJa7rcm7F3NDp+DLryAh6/yJRsXSlM2RcdkbvhD2Cvvd+YJCcD0LPht1Nibf91htvd2glUjoU4DpIUwd7RI8OvVH+QETXjO9

生成authorized_keys

➜  ~ ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/aron/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again:

Your public key has been saved in /Users/aron/.ssh/id_rsa.pub.
The key fingerprint is:

拷貝authorized_keys文件

➜  ~ cd ~/.ssh
➜  .ssh cp id_rsa.pub ~/authorized_keys

ios手機配置

退出ssh登陸，拷貝電腦的authorized_keys文件到iPhone中

iPhone:/User root# logout

➜  theos git:(master) ✗ scp ~/authorized_keys root@192.168.1.86:/var/root/.ssh

Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '192.168.1.86' (RSA) to the list of known hosts. root@192.168.1.86's password:

從新登陸，這時候就不須要密碼了，包括在tweak的時候也是不用繁瑣的密碼輸入步驟了。
