1. Convert your cert to a .pem file with the following instructions

Convert .crt and .key to .pem

"%VISUALSVN_SERVER%\bin\openssl" pkcs12 -export -in my.crt -inkey my.key -out my.p12
"%VISUALSVN_SERVER%\bin\openssl" pkcs12 -in my.p12 -nodes -out my.pem

Convert .pfx to .pem

"%VISUALSVN_SERVER%\bin\openssl" pkcs12 -in mycert.pfx -out mycert.pem -nodes

2. Copy the my.pem to “%VISUALSVN_SERVER%\certs”
3. Update “%VISUALSVN_SERVER%\conf\httpd.conf” to reflect the name of your .pem.
