Often, especially when dealing with both Windows and Linux servers, I have to convert from a format to another. Here are some commands to do so
CRT to PEM
Using Openssl on Windows 10 (Might be compatible with Linux machines as well, but you know, sometimes you need to adjust commands)
openssl x509 -in .\cs-root-01_CS-ROOT-01-CA.crt -inform der -outform pem -out myCert.pem
