Amazon launches the free cloud host server Amazon EC2, which accesses the host through a security key. The problem is that the downloaded key cannot be used directly on SECURECRT and needs to be converted. The following method can generate SECURECRT required keys on your own Linux host. The key pair is generated first in the AWS management panel.
Upload the key to one of your own Linux hosts, the following example file name Amazon-ec2-key.pem modifies the key file permissions provided by Amazon:
chmod og-r AMAZON-EC2-KEY.PEM rewrite key format for OpenSSH, if asked passphrase can be left blank (direct carriage return)
Ssh-keygen-p-F AMAZON-EC2-KEY.PEM generates a public key. pub file. When using the public key, SECURECRT will ask for a private key or a. pem file
SSH-KEYGEN-E-F Amazon-ec2-key.pem >> Amazon-ec2-key.pem.pub can now use the newly generated public key in SecureCRT, and the host that connects to Amazon no longer has to enter the password.
