But there was a previous assertion in this thread (by whom?) that the Apple docs say SecTransform doesn't support public-key crypto. I quickly looked through some docs but didn’t see a statement one way or another. This actually illustrates one of my major complaints about the current Apple security APIs and docs — they’re modular and operate on many combinations of small pieces (e.g. the different transform functions used with different key types, or the handful of keychain functions used with a combinatorial explosion of different parameter constants), but the docs provide almost no guidance on which of the many, many possible combinations of pieces work and which don’t. > Anyway, the full list of what can be done is demonstrated in the > CryptoCompatibility sample code: > https://developer.apple.com/library/mac/samplecode/CryptoCompatibility/Introduction/Intro.html > For each possible action, it provides a way to perform it using CDSA, > SecTransform, and iOS specific code. That sounds great, actually, but documentation of what can be done and what can’t really belongs in the core API docs, not in a piece of sample code that someone may never discover (I haven’t ever seen this one before myself.) —Jens _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
