Let’s Encrypt, the free and automated CA, started late last year into their public beta. They offer a pretty comprehensive client to automate the process of getting SSL clients and installing them. It will soon be moved to a new home at EFF.
Namecheap published a blog post recently explaining the difference between Namecheap’s paid SSL and other free CAs. They said they want to cover the facts, so I’ll write about the actual facts here.
