certgen

  `certgen` is a small utility for generating certificates.

Usage:

  

  certgen [domain [...]]

Requirements:

  - openssl

Example:

  

  Suppose we want to generate a certificate for `test.com`

  so that we can test an HTTP2 setup using HAProxy.

    ./certgen test.com

    INFO:

      Starting certificate generation.

      

      DOMAIN=test.com

      KEY_NAME=key_test.com.pem

      CERT_NAME=cert_test.com.pem

      HAPROXY_CERT=haproxy_test.com.pem

      OPENSSL_CONF=/var/folders/hb/wvttlxt51xl_m1wmtrj_k4sh0000gn/T/tmp.IdudKFSt

      

    Generating a 4096 bit RSA private key

    ..................++

    .......++

    writing new private key to 'key_test.com.pem'

    -----

    SUCCESS:

      Certificates successfully generated.

      You can inspect the certificate by issuing the following command:

        openssl x509 -in cert_test.com.pem -text -noout

    Done.

  Now that we have our certificate generated, run the inspection command:

    Certificate:

        ...

            Issuer: C=BR, ST=SaoPaulo, L=SaoPaulo, O=TestOrg, OU=TestUnit, CN=test.com

            Validity

                Not Before: Nov  8 12:31:51 2017 GMT

                Not After : Nov  8 12:31:51 2019 GMT

            Subject: C=BR, ST=SaoPaulo, L=SaoPaulo, O=TestOrg, OU=TestUnit, CN=test.com

            ...

                RSA Public Key: (4096 bit)

                        ...

                X509v3 Subject Alternative Name: 

                    DNS:test.com

        ...

    Check that Chrome takes the certificate:
