XAMPP

How to Create Valid SSL in localhost for XAMPP

1. Navigate to Apache directory in XAMPP.

In regular install it’s in C:\xampp\apache.

2. Create a folder in that page.

This is where we will store our cert. In this example I will create “crt” folder. So we will have C:\xampp\apache\crt

3. Add this files.

cert.conf

@echo off
set /p domain="Enter Domain: "
set OPENSSL_CONF=../conf/openssl.cnf

if not exist .\%domain% mkdir .\%domain%

..\bin\openssl req -config cert.conf -new -sha256 -newkey rsa:2048 -nodes -keyout %domain%\server.key -x509 -days 365 -out %domain%\server.crt

echo.
echo -----
echo The certificate was provided.
echo.
pause
make-cert.bat
[ req ]

default_bits        = 2048
default_keyfile     = server-key.pem
distinguished_name  = subject
req_extensions      = req_ext
x509_extensions     = x509_ext
string_mask         = utf8only

[ subject ]

countryName                 = Country Name (2 letter code)
countryName_default         = US

stateOrProvinceName         = State or Province Name (full name)
stateOrProvinceName_default = NY

localityName                = Locality Name (eg, city)
localityName_default        = New York

organizationName            = Organization Name (eg, company)
organizationName_default    = Example, LLC

commonName                  = Common Name (e.g. server FQDN or YOUR name)
commonName_default          = {{DOMAIN}}

emailAddress                = Email Address
emailAddress_default        = [email protected]

[ x509_ext ]

subjectKeyIdentifier   = hash
authorityKeyIdentifier = keyid,issuer

basicConstraints       = CA:FALSE
keyUsage               = digitalSignature, keyEncipherment
subjectAltName         = @alternate_names
nsComment              = "OpenSSL Generated Certificate"

[ req_ext ]

subjectKeyIdentifier = hash

basicConstraints     = CA:FALSE
keyUsage             = digitalSignature, keyEncipherment
subjectAltName       = @alternate_names
nsComment            = "OpenSSL Generated Certificate"

[ alternate_names ]

DNS.1       = {{DOMAIN}}

4. Edit cert.conf and Run make-cert.bat

Change {{DOMAIN}} text using the domain we want to use, in this case site.test and save.

Double click the make-cert.bat and input the domain site.testwhen prompted. And just do enter in other question since we already set the default from cert.conf.

Note: I don’t know how to do text replace in .bat script, if you do, let me know in the comment how to do it and I will update make-cert.bat to automatically replace the {{DOMAIN}} with the domain input.

5. Install the cert in windows.

After that, you will see site.test folder created. In that folder we will have server.crt and server.key. This is our SSL certificate.

Double click on the server.crt to install it on Windows so Windows can trust it.

And then select Local Machine as Store Location.

And then Select “Place all certificate in the following store” and click browse and select Trusted Root Certification Authorities.

Click Next and Finish.

And now this cert is installed and trusted in Windows. Next is how how to use this cert in XAMPP.

6. Add the site in Windows hosts

  1. Open notepad as administrator.
  2. Edit C:\Windows\System32\drivers\etc\hosts (the file have no ext)
  3. Add this in a new line:
127.0.0.1 site.test

This will tell windows to load XAMPP when we visit http://site.test You can try and it will show XAMPP dashboard page.

7. Add the site in XAMPP conf.

We need to enable SSL for this domain and let XAMPP know where we store the SSL Cert. So we need to edit C:\xampp\apache\conf\extra\httpd-xampp.conf

And add this code at the bottom:

## site.test <VirtualHost *:80>     DocumentRoot "C:/xampp/htdocs"     ServerName site.test     ServerAlias *.site.test </VirtualHost> <VirtualHost *:443>     DocumentRoot "C:/xampp/htdocs"     ServerName site.test     ServerAlias *.site.test     SSLEngine on     SSLCertificateFile "crt/site.test/server.crt"     SSLCertificateKeyFile "crt/site.test/server.key" </VirtualHost>

After that, you will need to restart Apache in XAMPP.  It’s very simple, simply open XAMPP Control Panel and Stop and re-StartApache Module.

Tips: In XAMPP conf, as you can see you can change the domain root directory if needed. Eg. as sub-dir in htdocs.

8. Restart your browser and Done!

This is required to load the certificate. And visit the domain on your browser, and you will see green lock!
