How to issue an SSL certificate

Recently doing how to make the website have SSL, have a day, now summarize

The first thing to do is to install OpenSSL and Java Keytool

Generate private keys and CSRs with OpenSSL first

openssl req -newkey rsa:2048 -nodes -keyout domain.key -out domain.csr

You will be prompted to enter some information at the time of generation, remember to enter the information of the domain name to be authenticated in common name, such as Xxx.xxx.com

After the build, the CSR information is opened in Notepad, the information is entered into the CA certificate publisher's website, and then the certificate signed

After the completion of the name may send a compressed file to you, I use the Comodo certificate

Contains 3 files

Domain.ca-bundle

Domain.crt

domain.p7b

Must go to their website to download, they will only email you send two files, one is domain.ca-bundle another is DOMAIN.CRT

The rest is to convert p7b to PFX.

Convert p7b to CER first

OpenSSL pkcs7-print_certs-in domain.p7b-out domain.cer

Then generate a PFX with the previous generation and signature of the private and CER files

OpenSSL pkcs12-export-in Domain.cer-inkey domain.key-out domain.pfx

If you are using Tomcat,tomcat to support PFX, but I like to build it jks, so take one step

Keytool -importkeystore -srckeystore domain.pfx -srcstoretype pkcs12 -destkeystore domain.jks -deststoretype jks

Then add this certificate in Tomcat's server.xml to start the certificate and you can use the
