How can I convert .crt to .pem?
回答1:
You can do this conversion with the OpenSSL library
http://www.openssl.org/
Windows binaries can be found here:

Once you have the library installed, the command you need to issue is:
openssl x509 -in mycert.crt -out mycert.pem -outform PEM
回答2:
I found the OpenSSL answer given above didn't work for me, but the following did, working with a CRT file sourced from windows.
openssl x509 -inform DER -in yourdownloaded.crt -out outcert.pem -text
