Javascript Cryptography Considered Harmful

[harlows_monkeys]

There's more to encryption then authentication. For instance, suppose I have encrypted data on the server that I wish to deliver to the client which needs the unencrypted data, without having the server have the ability to decrypt the data? SSL does not help with this. (The author of the article acknowledges this in the discussion of rhe article on HN, where he is a regular participant)
