[edit] Terminology

• Certificate Authority File
• Certificate Chain File: looks like this is a concatenation of the certificates which form a chain from your domain back to the root.
  • It's not clear whether they need to be in order or not.
  • It's not clear whether this terminology is HSphere-specific or in general usage.
  • Apparently the root certificate can be included but is optional.

[edit] Notes

• openssl verify [1] seems to be the tool of choice for checking certificate files stored locally.
• This also has some useful information about using openssl, and a little bit about the "chaining" concept.
