Hi Jack,  
Even I am looking for a .crt, .key, .ca-bundle files however I can only see .pem files inside /etc/letsencrypt/archive/ directory.

-rw------- 1 root root 1708 May 30 23:38 privkey.pem  
-rw-r--r-- 1 root root 5629 May 30 23:38 fullchain.pem  
-rw-r--r-- 1 root root 3750 May 30 23:38 chain.pem  
-rw-r--r-- 1 root root 1879 May 30 23:38 cert.pem

Based on my google search I think that the following commands would give me a .key file, a .cert file, however, I am unable to understand where would I get a .ca-bundle file.

openssl x509 -outform der -in cert.pem -out certificate.crt  
openssl pkey -in privkey.pem -out privkey.key

Can you please help me figure out where would I get a .ca-bundle file ?

There is no difference between a .crt file and a .pem file, and you don't need to do anything to the files you have. What you're calling the .key file is `privkey.pem`. What you're calling the .crt file is `cert.pem`. And what you call .ca-bundle is `chain.pem`.
