Generate a Key Pair

Run the following commands at a Linux or macOS command line to generate a key pair consisting of a private key and a public key.

openssl genrsa -out private.key 4096

This command generates a private key in the specified location (in this case, because no file path was provided, the private key is generated in the current directory, in a file named private.key). Next you need to extract the public key, which is shared with StrongDM to encrypt logs and other data.

openssl rsa -pubout -in private.key -out public.pem

If you look at public.pem you see text similar to the following:

-----BEGIN PUBLIC KEY-----

-----END PUBLIC KEY-----

This data is what you copy and paste into the StrongDM Admin UI when you turn on encryption at the StrongDM gateway and/or relay level and choose to use your own public key. Remember to copy and paste the entire contents of the key into the text box, including the lines: -----BEGIN PUBLIC KEY----- and -----END PUBLIC KEY-----

Store your private key (private.key by default) in a safe place. If you lose this key you cannot decrypt your logs, queries, and sessions.
