How to obtain public-key.pem file to be used for Oauth2 Client

[NilotpalM]

I am creating Oauth 2 client in SAP Successfactors using "Manage Oauth2 Client" option. I got a X.509 certificate which has a private key within it and a certificate. How should I extract the public key pem file from this? I am using openssl command like below for extracting but getting an error:

Command:

openssl x509 -pubkey -noout -in cert.pem > pubkey.pem

Error:

Could not read certificate from Certificate.pem

The private and public key pem files are required for me to get the SAML Assertion using the sf-oauth(https://www.npmjs.com/package/sf-oauth#generate-via-cli) npm utility.

Hello,

I haven't had this error before, but maybe the command should be rather

openssl pkey -pubout -in privkey.pem -out pubkey.pem

?

Is it possible to read the content with:

openssl x509 -text -in cert.pem

?

Or try using a different version of openssl?
