1. go to modules\http\Apache-PHP-7-x64\conf and edit generate.bat @echo off set OPENSSL_CONF=%~dp0..\conf\openssl.cnf ..\bin\openssl req -x509 -sha256 -newkey rsa:2048 -nodes -days 5475 -keyout rootCA.key -out rootCA.crt -subj "/CN=OSPanel/" ..\bin\openssl req -newkey rsa:2048 -nodes -days 5475 -keyout server.key -out server.csr -subj "/CN=PhpStorm/" ..\bin\openssl x509 -req -sha256 -days 5475 -in server.csr -extfile v3.txt -CA rootCA.crt -CAkey rootCA.key -CAcreateserial -out server.crt ..\bin\openssl dhparam -out dhparam.pem 2048 2. In same folder, create v3.txt and add new domain (test.osp for this example). nsComment = "Open Server Panel Generated Certificate" basicConstraints = CA:false subjectKeyIdentifier = hash authorityKeyIdentifier = keyid,issuer keyUsage = nonRepudiation, digitalSignature, keyEncipherment subjectAltName = @alt_names [alt_names] DNS.1 = eba.test DNS.2 = www.eba.test DNS.3 = sales.test DNS.4 = www.sales.test DNS.5 = reports.test DNS.6 = www.reports.test DNS.7 = test.test DNS.8 = www.test.test DNS.9 = localhost DNS.10 = www.localhost DNS.11 = pia.test DNS.12 = www.pia.test DNS.13 = 3march.test DNS.14 = www.3march.test DNS.15 = 127.0.0.1 DNS.16 = www.127.0.0.1 DNS.17 = mystuff.test DNS.18 = www.mystuff.test DNS.19 = banners.test DNS.20 = www.banners.test DNS.21 = digest.test DNS.22 = www.digest.test DNS.23 = ads.clp.ge DNS.24 = localhost DNS.25 = funtime.test DNS.26 = www.funtime.test DNS.27 = newscms.test DNS.28 = www.newscms.test DNS.29 = spellcheck.test DNS.30 = www.spellcheck.test DNS.31 = tbiliselebi.test DNS.32 = jt.test DNS.33 = www.jt.test DNS.34 = laravel.test DNS.35 = www.laravel.test DNS.36 = dev.test DNS.37 = www.dev.test DNS.38 = grand.test DNS.39 = www.grand.test DNS.40 = odr.test DNS.41 = www.odr.test DNS.42 = eba-mac.test DNS.43 = www.eba-mac.test DNS.44 = odr.test DNS.45 = quiz.test DNS.46 = www.quiz.test DNS.47 = auu.test DNS.48 = www.auu.test DNS.49 = crud.test DNS.50 = vuejs.dev DNS.51 = www.vuejs.dev DNS.52 = quizz.test DNS.53 = www.quizz.test 3. In cmd, go to this location and execute generte.bat cd modules\http\Apache-PHP-7-x64\conf generate.bat 4. Than, replace exsisting cert files in userdata or change location of ssl in conf files. 5. Add newly generated files in "Trusted root". DONE
