This is simple project that shows how to setup a TLS communication between server and client using openssl
I already generated rootca and the certificates for localhost
in order to allow fast tests of the application. I also included the rootCA key in git in case you want to reuse it BUT remember: NEVER EVER PUBLISH THE rootCA KEY file.
You can use the following bash snippets to generate your own certificates.
- Generate the private key of the root CA:
openssl genrsa -out rootCAKey.pem 2048
- Generate random password for the certificate:
openssl rand -hex 32 > password
Note that this snippet will generate a certificate for localhost
. If you want to change domain replace localhost
with the desired domain.
- Generate the certificate key encrypted with the password in password:
openssl genrsa -aes256 -passout pass:$(cat password) -out certificate.key 2048
- Generate the public certificate for localhost:
openssl req -new -days 3650 -x509 -key certificate.key -passin pass:$(cat password) -out certificate.pem -subj "/C=IT/ST=Italy/L=Milan/O=MazerFaker/OU=Engineering/CN=localhost"
If you have some issue with the certificates you can use this site to debug it.
