I'd like to convert an existing public key (generated using
openssl rsa -in ~/.ssh/id_rsa.pub -inform PEM -pubin -outform DER -out ~/.ssh/id_rsa.pub.der
Unfortunately this gives the following error:
unable to load Public Key 139946985690784:error:0906D06C:PEM routines:PEM_read_bio:no start line:pem_lib.c:703:Expecting: PUBLIC KEY
~/.ssh/id_rsa.pub contains a public key;
cat ~/.ssh/id_rsa.pub gives:
ssh-rsa ...... user@machine
What am I doing wrong?
