I have an existing web site that I created on a Raspberry Pi at home and have locked it down with a self-signed certificate. I have been getting by fine because I've been using an older browser that allows me to accept the certificate and continue on to the site. However, the newer browsers don't allow that and just deny any access at all which is making it impossible for a friend of mine to connect to the site. So, I've started looking into getting a real server certificate which is leading to a chain of expenses that I would rather not incur. Server certs require a domain name which then costs a yearly fee. I've looked at several domain name sites and there seems to be a lot of hidden fees, add-ons and other expensive gotchas that you have to watch for. My question is whether there are alternatives to what I'm trying to solve (accessibility) or what is the cheapest way to get a valid certificate on my server that will be recognized properly by most browsers. I have looked at https://letsencrypt.org/certificates/âââ [Broken] for free certs and several domain name sites for purchasing a domain. GoDaddy is cheap for the first year and gets expensive the following years. You also have to pay an extra yearly fee to keep your personal info off of the whois directory. I also looked at Namecheap.com that seems to be a better deal and allows private whois registration. However, I have no experience with these things and could really use some advice from those who have been through this. Thanks in advance.
