I’m really bad at all this SSL stuff, hence please excuse me if my question sounds silly.
My client has requested us to provide them with a .crt and .key (private) file from our hosting provider (WPEngine) in order to be able to redirect from their domain to our domain. The .crt file needs to be in the following specs:
- .crt file in PEM format for nginx/apache server
- SHA 256
- 2K length
Upon chatting with WPEngine, they can only provide me with a .csr and .key (private key) file as they do not have the tools to convert it to .crt (PEM). Upon googling on how to get this .crt file, I have found out that this .crt file needs to be generated by a valid CA.
Is this something that LetsEncrypt can do? I would appreciate if someone could point me in the right direction (with the steps please) on how I should acquire this .crt file with private key in the above-mentioned specs.
