配置华为设备使用SSH公钥登录

• 使用openssh格式公钥

aaa

ssh user admin authentication-type all
rsa peer-public-key tao encoding-type openssh
public-key-code begin

dis rsa peer-public-key
ssh user admin assign rsa-key tao

• 使用华为专有格式的公钥
  有些华为设备或固件版本不支持openssh格式公钥，只能使用华为格式
  执行ssh-keygen -e -m pem -f ~/.ssh/id_rsa.pub | sed '1d;$d' | tr -d '\n' | base64 -d | od -t x1 -An | tr -d ' \n' | tr 'a-f' 'A-F' | sed 's/\(.\{8\}\)/\1 /g' | fold -w 54把本地openssh格式的公钥转换为华为格式

ssh user admin authentication-type all

注意：
复制密钥的时候不要漏掉后面的尾巴，尤其是复制华为16进制密钥格式时，因为末尾没有换行容易忽略
