I'm trying to set up an Avalance node on AWS. When following the instructions to set up a key pair, the file generated was a .cer file instead of a .pem file. Will I still be able to SSH onto the instance?

I'm on a mac and I'm not able to get the SSH to work. I don't know, however, what the issue is. It's not giving me an error. It's just sitting there with no response.

Got the instructions here: https://docs.avax.network/build/tutorials/nodes-and-staking/setting-up-an-avalanche-node-with-amazon-web-services-aws/

Convert a DER file (.crt .cer .der) to PEM

openssl x509 -inform der -in certificate.cer -out certificate.pem

  • I ended up just changing the extention from .cer to .pem using finder in my Mac. Seems to work. Is that gonna compromise my security? – DBWeinstein Jan 05 '22 at 00:19
