Re: Key recovery methods?

After reading through the CDSA and CSSM v2 with Corrigenda again, I read more closely in the Key Recovery section. Are we supposed to be specifically using CSSM_KR_CreateRecoveryEnablementContext / CSSM_KR_GenerateRecoveryFields for the use of CSSM_EncryptData / CSSM_DecryptData?
Well, the entire key recovery section of the CDSA standard isn't currently implemented on Mac OS X. In fact, the CSSM_KR_* functions don't currently exist in Security.framework. So you should probably not try to call them. :-)
We’re not now, but I’d like to know whether we’ll run into problems eventually if this remains the case, and if so, when is it likely to make a difference.
Apple has a policy of never commenting on unannounced features. It is however certainly a fact that Apple has not expressed any intent to implement this for Leopard. I might note, parenthetically, that you're the first person in five years to ask about CDSA key recovery, which might give you an idea of how high a priority this could be.

If we ever go ahead and implement that, I'd assume that we'd let developers know in plenty of time to make any necessary changes or additions.
