RavenDB 4.x is using X509 Certificates for authentication. We got a feedback question from a customer about that, they much rather to use API Keys, instead.
We actually considered this as part of the design process for 4.x and we concluded that we can make this work in just the same manner as API Keys. Here is how you can make it work.
You have the certificate file (usually PFX) and convert that to a Base64 string, like so:
[System.Convert]::ToBase64String( (gc "cert.pfx" -Encoding byte ) )
You can take the resulting string and store it like an API key, because that is effectively how it is treated. In your application startup, you can use:
And this is it. For all intents and purposes, you can now use the certificate as an API key.
