The article at http://www.net-security.org/article.php?id=1322 claims that both are easily broken. I haven't been able to find any public analyses of Keychain, even though the software is open-source so it's relatively easy to check. I ran across an analysis of File Vault not long ago which pointed out some fairly minor nits, but basically claimed it did what it set out to do.

The article makes a bunch of other claims which aren't obviously unreasonable.

Anyone one know of more recent analysis of Mac encryption stuff? (OS bugs/security holes are a whole other story....)
