EC-384 Certificates? Maybe? Yes? No? Here's an entry on Namecheap's website regarding supposed ec-384 certificates users can purchase
https://www.namecheap.com/support/knowledgebase/article.aspx/9504/38/how-do-i-get-an-ecc-certificate-via-namecheap This is being shared here because most of us in this world have made chosen to go the financially fiscal route for obtaining + deploying certificates (LetsEncrypt).
Unfortunately, 'LetsEncrypt' still uses an intermediate C.A. that signs keys with an RSA private key (its 4096-bit, so not a major security drawback).
Obviously with ECC being all the rage (despite people wishing Edwards' Curves were), there's been a major shift in the industry over the past few years to begin adopting ECC-standards in cryptography based products.
Unable to Locate the EC-Strength Cerificates Namecheap claims that these certificates are provided for by Comodo, but we were unable to find them on their site (namecheap) or via Comod's site either.
Admittedly, we didn't dig incredibly hard for them, but we'll try to remember to follow up on this and ask their sales reps about this.
The world of 'paid' for certificates is super gimmicky & commercialized (and this feels like something that shouldn't be...for some reason), but hey — its the best 'trust' system that we have at our disposals for right now.
