Hi Robert:
Thanks so much for your response. Unfortunately, I don't know what the
specific product is . . . However, below is the description that I do
have:
"POSIX Access Control Lists -- used to define more fine-grained
discretionary access rights for files and directories."
Given that POSIX ACLs are an access control mechanism, do they contain
any algorithms that perform authentication/password protection?
Thanks,
Erin

Hi Erin--
The answers to these questions will be specific to the product you are
considering, open source or otherwise. If you could let us know what
specific software you're looking at, perhaps we could point you in the
right direction (for example, is it FreeBSD?). However, in the general
case, POSIX.1e ACLs are a local file system access control mechanism
unrelated to cryptography, and are therefore unlikely to involve
cryptography in their implementation.
