-m formatThe supported key formats are: “RFC4716” (RFC 4716/SSH2 public or private key), “PKCS8” (PKCS8 public or private key) or “PEM” (PEM public key). By default OpenSSH will write newly-generated private keys in its own format, but when converting public keys for export the default format is “RFC4716”.
https://man7.org/linux/man-pages/man1/ssh-keygen.1.html-t dsa | ecdsa | ecdsa-sk | ed25519 | ed25519-sk | rsa Specifies the type of key to create. The possible values are “dsa”, “ecdsa”, “ecdsa-sk”, “ed25519”, “ed25519-sk”, or “rsa”. This flag may also be used to specify the desired signature type when signing certificates using an RSA CA key. The available RSA signature variants are “ssh-rsa” (SHA1 signatures, not recommended), “rsa-sha2-256”, and “rsa-sha2-512” (the default).
ssh-keygen -i -f ssh2.pub > openssh.pub

Differences between “BEGIN RSA PRIVATE KEY” and “BEGIN OPENSSH PRIVATE KEY”
ProxyCommandhttp代理ssh(http over ssh)
## http 协议的代理
GIT_SSH_COMMAND='ssh -o ProxyCommand="nc -X connect -x 192.168.1.100:8118 %h %p"' git clone git@github.com:kubernetes/kubernetes.git
## SOCK5 协议的代理
GIT_SSH_COMMAND='ssh -o ProxyCommand="nc -X 5 -x 192.168.1.100:3000 %h %p"' git clone git@github.com:kubernetes/kubernetes.git
或者写入~/.ssh/config文件
Host github.com
HostName github.com
User git
ProxyCommand nc -X connect 192.168.1.100:8118 %h %p

第一次git clone ssh提示
The authenticity of host 'github.com (20.205.243.166)' can't be established.

Are you sure you want to continue connecting (yes/no)?
方式1
ssh-keygen -f "~/.ssh/known_hosts" -R github.com
ssh-keyscan -H github.com >> ~/.ssh/known_hosts
方式2
GIT_SSH_COMMAND="ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no" git clone user@host
方式3
GIT_SSH_COMMAND="ssh -o StrictHostKeyChecking accept-new" git clone user@host
