Have you ever noticed a green https:// near the website address name on
the browsers? If you had noticed, you are luckily aware of the internet
website security. https is a secure protocol version of http while http
is hyper text transfer protocol to view web documents across internet.
The https is enabled through obtaining a web security certificate from
Certificate Authority(CA).
The certificate authority is the one who verifies and validates your website and ensures the website is what it claims to be. There are many types of validations, namely, Domain Validation, Extended Validation etc. Some CAs provide wildcard certificates, i.e one certificate is enough to secure the web domain and all of its subdomains. For your information, All financial websites, banking sites use https protocol in order to protect customer information and avoid man in the middle attacks. They obtain https certificate from different CAs, mostly high expensive certificate providers. Ok. So, Is there any free Certificate Authority?
Yes, LetsEncrypt is an automated, free, open Certificate Authority provided by Internet Security Research Group(ISRG). The group intends to secure the website and make web a place for sharing safe and secure documents. It provides free Domain Validation(DV) Certificates. How to obtain a free DV certificate from LetsEncrypt CA?
LetsEncrypt works based on ACME protocol. There are many ACME clients available of which CertBot is popular. Using CertBot client, anyone can verify their domain and obtain a free DV certificate from LetsEncrypt for the period of 90 days. Once the validity is over, user can renew the certificate. Since the process of renewing cerificates can be automated, the LetsEncrypt certificates are more secure than commercial long validity certificate. Long validity Certificate is prone to security vulnerabilities due to the nature of prolongevity.
What should I do to get the LetsEncrypt Certificate running in my personal website? LetsEncrypt ACME clients can run based on standalone, apache or Nginx Servers. Apache based certificate generation is more stable than Nginx. First, we install CertBot and ensure the apache is running in our server. Make sure the domain address is pointing to the server address using A record in the DNS provider system. Once these are set, issue a certificate issuance command for the domain you want to get certificate for. That certbot will run LetsEncrypt agent to do its job.
The agent requests LetsEncrypt a DV certificate, in turn, LetsEncrypt puts set of challenges that the agent has to complete. The challenges are basically to know the domain is really controlled by the agent. Once the challenge is met, LetsEncrypt issues DV certificate for 90 days. After 90 days, the user can run renew certificate command to get another one. Since the automation of certbox is quite easy, user can do this in automated fashion.
What is more? LetsEncrypt is planning to issue wild card certificate starting Jan 2018. This means user can protect the domain as well as its subdomains free of cost.
Caveat: Since its free of cost, there is no guarantee of protection insurance like the ones provided by commercial CAs. This is only suitable for personal, non profit or non financial systems. If you think you don't need any security insurance and want a free of cost DV certificates, you have one, LetsEncrypt.
