Convert a AWS PEM into a ssh pub key

ssh.sh

ssh-keygen -y -f private_key1.pem > public_key1.pub 

Thanks.

the private and public key names has to match?

$ ssh-keygen -y -f private_key1.pem > public_something_else.pub

@scheung38 they do not

Gracias friend

thanks!

doesn't work, it says "Load key "pubkey.pem": invalid format"

doesn't work, it says "Load key "pubkey.pem": invalid format"

It's the same for me. Any ideas anyone?

@Faishal24 , @ricsaka , maybe you need to pass the param -m PKCS8

ssh-keygen -y -f private_key1.pem -m PKCS8 > public_key1.pub 

From the manual:

 -m key_format
        Specify a key format for the -i (import) or -e (export) conversion options.  The
        supported key formats are: “RFC4716” (RFC 4716/SSH2 public or private key), “PKCS8”
        (PEM PKCS8 public key) or “PEM” (PEM public key).  The default conversion format is
        “RFC4716”.

My solution to Load key invalid format was to use -i instead of -y
ssh-keygen -i -m PKCS8 -f cert.pem > cert.pub
