OpenSSL - Create ECDSA public certificate

A trusted certificate is one that is purchased from a trusted certificate authority (CA), such as www.verisign.com. Internet facing production applications should use a certificate from a trusted CA. For non-production applications, a self-signed certificate can be used.  Applications, such as a web browser, will complain when a self-signed certificate is used.

 


 

Use  apt-get or yum to install OpenSSL.

~]# apt-get install openssl
~]# yum install openssl

 


Private key

This assumes you've already created a private key, such as example.com.key. If not, refer to our article on creating a private key.

 


Certificate

Create an ECDSA certificate.

~]# openssl req -x509 -new -key /etc/pki/tls/private/ec_private.key -out /etc/pki/tls/certs/ec_certificate.crt

 

There will be a series of prompts.

Area Example Description
Password myPassword Password
Country Name US United States
State/Province FL Florida
Locality Name Miami City
Organization Name Example, Inc. Company name
Organization Unit Name Example, Inc. Company name
Common Name www.example.com Domain name
Email Address admin@example.com Admin email

 

View the content of the ec_certificate.crt file and ensure BEGIN CERTIFCATE is displayed.

~]# cat /etc/pki/tls/certs/certificate.crt
-----BEGIN CERTIFICATE-----
